Vitamin-M | CBSE Class 9 English Notes

This note covers Asha Nehemiah's story "Vitamin-M": a part-by-part summary, the characters, the themes, key quotations and answers to the textbook questions.

Who are the characters in "Vitamin-M"?

The story has a small cast built around one household, so each character's reaction to the others carries the plot.

Ravi is the narrator's focus: a boy enjoying his holidays who is suddenly put "in charge" of his grandfather and discovers, through an embarrassing day of amateur detective work, that the old man is far cleverer than anyone has given him credit for.

Who is Grandpa, and what kind of person is he?

Grandpa is seventy-five years old, a retired lawyer who has been "looking after" himself, cooking, shopping and keeping house since his wife died ten years earlier.

He is frail in body, holding the newspaper "inches from his nose," yet his mind for chess is "cool and cunning"; he remembers Karpov's and Bobby Fischer's historic games in detail.

He hates city "noise and bustle" and misses his quiet brick house with its mango tree.

He is also independent and proud, resenting being told he cannot go out alone, and quietly mischievous, as his final "twinkle in the eye" shows.

How does Ravi change over the course of the story?

Ravi begins as an obedient son who promises his mother, "Grandpa'll be fine at home with me," but he is also uneasy at her "over-loud tone" with Grandpa, sensing it is unfair.

Once Grandpa slips out, Ravi turns detective, following him through the park, the tea stall and onto a bus, enduring a bush-hiding incident and a mortifying dash into a Ladies' Hairdressing Salon.

By the end he is "confused and embarrassed," unsure whether Grandpa's twinkling eye means he was caught out all along.

What role does Ravi's mother, Vidya, play?

Vidya is caught between duty and anxiety. The month before the story opens, Grandpa took a double dose of medicine and got lost on a walk, so she has decided he "shouldn't go out alone again." She instructs Ravi firmly, "Whatever happens, Ravi, you're not to let Grandpa go out on his own.

It's too dangerous." Her anxiety is genuine, but Grandpa's sharp retort about being treated "like a baby" shows how such protectiveness can wound an elder's sense of dignity.

What happens in the story, part by part?

The story is printed in three numbered parts, each of which can be summarised in turn.

Part I: Who is Grandpa, and why is he living with Ravi's family now?

Ravi's mother wishes aloud for a "Vitamin-M" that would restore an old person's memory, not realising Grandpa, sitting nearby in his rocking chair, might overhear.

Ravi warns her to hush, but she says she doubts Grandpa can hear, see or remember well these days.

We learn that Grandpa came to live with them only a month earlier, after a difficult spell: he accidentally took a double dose of his medicines and had to be hospitalised, and on another occasion he got lost on a walk and forgot his way home.

Grandpa resents this loss of freedom, telling his daughter sharply that he had managed his own house for most of his seventy-five years and that she has "no right" to forbid him from going out.

He often speaks longingly of his quiet brick house in town, with its mango tree, contrasted with the "poky little flat" and "horrible, crowded city" he now lives in.

It was a fall in his own garden, after which he lay outside all night with no one to help him, that finally made Vidya lock up the house and bring him to the city.

Before leaving for work, Vidya repeats her warning to Ravi never to let Grandpa go out alone, speaking to Grandpa in a tone Ravi finds embarrassingly loud, as though to a child. Ravi promises to look after him.

When Ravi suggests a game of chess, in which Ravi has improved greatly since Grandpa arrived, Grandpa instead decides to walk to the corner shop for his Tamil newspaper.

Ravi offers to fetch it himself, but Grandpa, suspicious that he is being kept "a prisoner," insists on going and sets off with his walking stick and yellow cap, leaving Ravi in a dilemma about whether to stop him or follow him secretly.

Part II: What happens when Ravi secretly follows Grandpa?

Ravi trails Grandpa at a distance through the city. Grandpa first stops at the children's park to eat peanuts and watch the children, while Ravi hides comically behind a trimmed bush and is nearly caught by a small boy and then threatened by the boy's mother with an umbrella.

Next Grandpa visits a tea stall, where Ravi hides behind a banyan tree and is challenged by suspicious street vendors who think he is a rival seller encroaching on their spot.

From his hiding place behind a car, Ravi watches Grandpa break every rule set at home: sugary tea, two forbidden bananas, and an ice cream. Grandpa then crosses the busy road and enters a barber shop.

Guessing a haircut is pointless on a bald head, Ravi ducks into the shop next door to get a closer look, only to be thrown out amid shrieks because it turns out to be a Ladies' Hairdressing Salon.

He then sees Grandpa walking briskly to the bus stop and boarding a bus. Ravi sprints and jumps on just in time, but when he finally reaches the man in the yellow cap at the front, it is a total stranger, a kind gentleman to whom Grandpa had given his own cap, coffee-stain and all, because it was "such a hot day."

Part III: How is Grandpa found, and what happens afterwards?

Ravi rushes back to the barber shop and the park, but Grandpa is nowhere to be found. Unable to reach his parents by phone, Ravi returns home sick with worry, only to hear Grandpa snoring safely in his room.

Overcome with affection, Ravi hugs the sleeping old man and decides not to question him, since that would reveal he had been spying.

When Vidya returns, Grandpa calmly tells her that he had a "quiet morning" but does not know what Ravi was doing, since Ravi "just disappeared." Ravi looks "confused and embarrassed" but says nothing.

Grandpa then produces gift-wrapped parcels for everyone, explaining that he always gives gifts to every child in the house on his own birthday, which Vidya had forgotten despite having circled it on the calendar.

He also remarks pointedly that his daughter "needs some Vitamin-M… for her memory," turning her own wish from the opening scene back on her.

Ravi's gift is a book of detective stories, which Grandpa says will teach him "how to avoid getting fooled when one is trailing a suspect." The story ends with Ravi wondering whether the twinkle in Grandpa's eye is innocent or deeply mischievous, leaving open whether Grandpa knew all along that he was being followed.

What themes does the story explore?

Why does the story focus on dignity and independence in old age?

Grandpa's central complaint is not about safety but about losing control over his own life.

He reminds Vidya that he managed cooking, shopping and housekeeping alone for most of his seventy-five years, and bristles at being forbidden to walk to the corner shop.

His secret outing, breaking every household rule about sugar and sweets, is a small act of reclaiming independence, showing how restrictions meant to protect the elderly can feel to them like imprisonment.

How does the story show care, concern and the generation gap?

Vidya's anxiety comes from real past danger: Grandpa's double dose of medicine, his getting lost, and his overnight fall in the garden. Yet her "over-loud tone," as though speaking to a child, embarrasses Ravi and offends Grandpa.

The story balances a daughter's genuine worry against a father's wish to be treated as an adult, suggesting that caring for the elderly needs patience and respect, not just supervision.

What does the story suggest about memory, forgetfulness and irony?

The whole story plays on the idea of "Vitamin-M" for memory. Grandpa appears forgetful in small ways, needing his newspaper inches from his nose, yet he remembers decades-old chess games in precise detail and never forgets his own birthday tradition of giving gifts.

It is Vidya who has forgotten her father's birthday despite circling it in red on the calendar, so Grandpa turns her joke back on her, suggesting that forgetfulness is not only an old person's failing.

How does humour work alongside the story's message?

Ravi's clumsy attempts at detective work, hiding behind an elephant-shaped bush, being chased by vendors, stumbling into a Ladies' Hairdressing Salon, and following the wrong man onto a bus, give the story a comic tone even as it deals with a serious subject.

The humour never mocks Grandpa; instead it highlights how resourceful and self-sufficient he remains, undercutting the family's assumption that he is helpless.

What are the key quotations from "Vitamin-M"?

These short lines carry the story's main turns, from Vidya's opening wish to Grandpa's closing joke about her own memory.

"I wish… that somebody would invent a memory — Vitamin-M, they could call it." (Ravi's mother, opening the story)

"I've been looking after myself for the better part of my seventy-five years." (Grandpa, to his daughter)

"It is so quiet that at dusk you can even hear a leaf fall!" (Grandpa, recalling his old house)

"Whatever happens, Ravi, you're not to let Grandpa go out on his own." (Vidya, instructing Ravi)

"My daughter needs some Vitamin-M, I think—for her memory." (Grandpa, to Ravi's father)

"How to avoid getting fooled when one is trailing a suspect, for instance." (Grandpa, giving Ravi his gift)

Each quotation marks a shift in who holds the upper hand in the story. Grandpa, who seems forgetful at the start, remembers chess games from decades ago and his own birthday tradition exactly, while it is Vidya who forgets her father's birthday despite circling it on the calendar. The humour builds from Ravi's embarrassment, "shhh, shhh" said twice to an angry mother with an umbrella and to suspicious vendors, to Grandpa's calm, dry remark that turns the family's running joke about memory back onto his daughter.

What are the answers to the textbook questions?

Why did Grandpa dislike living in the city with his daughter?

Grandpa hated the "noise and bustle" of city life and missed his quiet brick house in town with its mango tree, "so quiet that at dusk you can even hear a leaf fall." He also disliked living in what he called "this poky little flat" in a "horrible, crowded city."

Why did Vidya not want her father to go out alone?

The previous month, Grandpa had taken a double dose of his medicines and had to be hospitalised, and on another occasion he got lost while on a walk and forgot the way home.

He had also fallen in his garden one evening and lain outside all night with no one to help him. These incidents made Vidya fear for his safety if he went out alone.

Was Ravi in favour of his mother treating Grandpa like a child?

No. Ravi "winced at the over-loud tone his mother used when speaking to Grandpa, as though she were speaking to a child who couldn't hear or understand too well," showing he disapproved of this manner even though he did not say so aloud.

Was Grandpa lost, as Ravi's mother had feared?

No. Grandpa was not lost; he simply went about his usual outing of park, tea stall and barber shop, and gave his yellow cap to a stranger in the barber shop because it was a hot day, which is what briefly confused Ravi into thinking something had gone wrong.

Why was Ravi worried about what Grandfather had at the tea stall?

Grandpa drank sugary tea, which was "forbidden sugar at home," ate two bananas, "another banned item," and then had an ice cream, all things his mother would "faint" to see him consume, so Ravi was anxious about the effect on Grandpa's health and about what his mother would say.

Was Grandfather aware that Ravi was following him?

The story leaves this deliberately open, but the ending hints that he may have been.

Grandpa's gift of a detective-stories book, with the comment about "getting fooled when one is trailing a suspect," and the ambiguous "twinkle in Grandpa's eye," suggest he may have known all along, though the text never confirms it outright.

In your opinion, who needs Vitamin-M, and why?

The story's irony suggests that Vidya herself needs "Vitamin-M," since she forgot her own father's birthday despite having circled it on the calendar, while Grandpa, supposedly the forgetful one, never forgets it and remembers chess games from decades earlier in exact detail.

Why does Ravi decide to follow Grandpa secretly?

When Grandpa insists on walking to the corner shop alone, Ravi is "left in a dilemma." If he insists on accompanying Grandpa, his grandfather will feel hurt and watched; if he lets him go entirely unsupervised, Vidya will be "furious" if she finds out.

Ravi's compromise, to follow "secretly, at a safe distance," tries to satisfy both loyalties at once.

This decision drives the whole comic middle section of the story. Ravi is not acting out of distrust of Grandpa's abilities; he genuinely believes Grandpa might be in danger, remembering the hospital visit and the lost walk from the month before.

His secrecy, however, is also a sign that he knows Grandpa would object to being supervised, which is exactly the loss of independence Grandpa resents.

The plan backfires comically: Ravi ends up more exposed to embarrassment, nearly caught by children and vendors, than Grandpa is to any real danger.

By the time Ravi loses track of Grandpa on the bus, it is Ravi, not Grandpa, who is "frantic" and unable to reach his parents by phone.

The irony is sharpened when Ravi finds Grandpa safely asleep at home, snoring gently, having managed his whole outing without the "protection" Ravi tried to provide.

This sequence quietly questions whether constant supervision of an elderly person is as necessary, or as effective, as the family assumes.

What does the story suggest about caring for the elderly?

"Vitamin-M" does not offer a single lesson about elder care; instead it shows the tension between safety and dignity.

Vidya's fears are grounded in real incidents: the double medicine dose, the lost walk, and the overnight fall in the garden. So her caution is not unreasonable, even though she expresses it in an "over-loud tone," as though speaking to "a child who couldn't hear or understand too well."

Grandpa's outburst about being treated like a "prisoner" in "this poky little flat" shows how restriction, even when well-meant, can feel humiliating to someone used to independence. He reminds Vidya that he managed his own cooking, shopping and housekeeping for most of his seventy-five years, including after his wife's death ten years earlier.

The story suggests that genuine care includes listening and respect, not only supervision. Ravi's instinctive wince at his mother's loud, simplified tone hints that children can sense this imbalance even when adults do not.

At the same time, Grandpa's own resourcefulness, enjoying his forbidden sugar, bananas and ice cream, giving away his cap to a stranger because "it was such a hot day," and remembering his birthday ritual precisely, shows that he is far more capable than the family's anxious talk of "Vitamin-M" implies.

The story's gentle message is that the elderly often need to be trusted with small freedoms as much as they need to be looked after, and that, as the ending shows, forgetfulness is not only an old person's failing.

How does the story use humour and irony together?

Much of the story's comedy comes from role reversal: it is Ravi, the supposed guardian, who ends up crouching behind an elephant-shaped bush, threatened with an umbrella by an angry mother, surrounded by suspicious vendors behind a banyan tree, and finally having to "crawl out of the park on all fours," while Grandpa calmly goes about his day unharmed.

This physical comedy is built from a string of small misadventures rather than one big joke: the park, the tea stall, the wrong shop, and the wrong man on the bus.

The deeper irony is verbal rather than physical. Vidya's opening wish for a memory pill, "Vitamin-M," is aimed at Grandpa, whom she says "doesn't hear too well, or see too well, or even remember too well these days." Yet it is she who forgets her own father's birthday despite having circled it on the calendar "at the beginning of the year" and written "Papa's birthday" beside it.

Grandpa's dry remark, "My daughter needs some Vitamin-M, I think—for her memory," turns the joke back on its maker, leaving Ravi's mother to flush "a darker shade of red."

Even the detective-stories gift to Ravi carries a double meaning: it praises Ravi's efforts at "trailing a suspect" while also hinting, through Grandpa's "solemn" tone and the final twinkle in his eye, that the "suspect" may have spotted his pursuer all along. The humour throughout rewards close attention to who really knows what.

What is the significance of the title "Vitamin-M"?

The title comes directly from Vidya's opening wish for an invented vitamin that could restore "memory" to old people, said while she puts out Grandpa's tablets and believes he cannot hear her.

On its surface, the phrase sets up Grandpa as the story's forgetful figure, someone who cannot "hear too well, or see too well, or even remember too well." This expectation shapes how Ravi, and the reader, first view him, especially after the double medicine dose and the lost walk of the previous month.

By the story's end, the title has been turned into an ironic joke rather than a literal need.

Grandpa proves his memory is sharp where it matters to him: he recalls Karpov's opening move against the computer and Bobby Fischer's historic match against Spassky in precise detail, and he never forgets his own birthday gift-giving tradition, where he gives presents to "every child in the house" rather than receiving them. It is Vidya who forgets her father's birthday, despite marking the date on the calendar.

Grandpa's closing line, suggesting his daughter needs "Vitamin-M… for her memory," reclaims the phrase and redirects it, showing that forgetfulness in the story belongs as much to the supposedly sharp younger generation as to the old.

How does the setting contrast Grandpa's old life with his new one?

The story draws a clear contrast between Grandpa's remembered life and his present one. His old home is a "small brick house in town" with a mango tree, so quiet that "you can even hear a leaf fall" at dusk.

His present home is a "poky little flat" in a "horrible, crowded city," full of the "noise and bustle" he dislikes.

This contrast is not just nostalgic description; it explains Grandpa's behaviour throughout the story. His insistence on walking to the shop alone, and his enjoyment of forbidden snacks once outside, read as small attempts to recover a sense of freedom he associates with his old, independent life.

The fall that forced the move, slipping while "pottering around" in his own garden and lying outside all night with no one to help him, is the one piece of evidence that his family's caution is not baseless.

The story does not resolve this tension between the quiet independence Grandpa misses and the safety his family wants for him; it simply presents both sides clearly enough for the reader to weigh them.

What makes Ravi's detective adventure comic rather than serious?

Ravi's pursuit of Grandpa is built from a series of small, escalating embarrassments rather than any real danger.

He hides behind a bush "trimmed in the shape of an elephant" and is nearly exposed by a small child who offers to show him "a better place to hide." A furious mother threatens him with an umbrella.

Street vendors selling combs, ribbons and clips surround him, suspecting he is a rival seller.

The comedy builds further when Ravi, trying to get a closer look at Grandpa in the barber shop, blunders into a Ladies' Hairdressing Salon and is evicted "amidst a volley of feminine shrieks." His final mistake, sprinting onto a bus and confronting a man in an identical yellow cap, only to find he has followed the wrong person entirely, is the comic high point of his failed detective work.

Each incident keeps raising the stakes of Ravi's embarrassment while Grandpa himself remains completely unaware of being followed, at least as far as the text directly shows, which keeps the tone light rather than alarming.

Common errors and misconceptions

• Misconception: Grandpa is genuinely forgetful throughout the story. Correct: He forgets small things like faces, but remembers chess games and his own birthday tradition precisely; the story uses this to question who really needs "Vitamin-M."
• Misconception: Ravi successfully follows Grandpa the whole way without being noticed. Correct: He is nearly caught by a child, threatened by a woman with an umbrella, and challenged by vendors, and he follows a stranger onto the bus by mistake.
• Misconception: Grandpa is lost at the end of Part II. Correct: He is not lost; he simply gave his cap to a stranger because it was hot, and Ravi only loses sight of him.
• Misconception: Vidya's strictness is shown as unreasonable or wrong. Correct: Her worry is grounded in real past incidents (the double medicine dose, getting lost, the overnight fall); the story presents her caution sympathetically alongside Grandpa's wish for independence.
• Misconception: Grandpa's birthday gifts are meant for himself. Correct: He gives a gift to every child in the house on his own birthday, a tradition his daughter had forgotten despite marking the date on the calendar.
• Misconception: The story confirms that Grandpa knew Ravi was following him. Correct: This is left ambiguous; the detective-stories gift and the "twinkle" in his eye only hint at it.
