Vitamin-M (Kaveri Unit 4): Irony, Humour and Role Reversal in the Chase

Updated 17 October 2026 · Fact-checked

In Vitamin-M by Asha Nehemiah, Ravi secretly follows his seventy-five-year-old Grandpa through the city, believing he is protecting him. In the end Grandpa has outwitted him, and it is Ravi's mother, who forgot Grandpa's birthday, who needs the "memory vitamin". The story is built on irony and role reversal, and it ends with a joke on those who think old age means a weak mind.

Understand Vitamin-M: Irony, Humour and Role Reversal in Ravi's Chase

The opening situation. Ravi's mother Vidya wishes someone would invent a "memory vitamin", Vitamin-M, for old people. Her father, a retired lawyer, has been forgetful: in the month since he moved in, he took a double dose of medicine and once got lost on a walk. She tells Ravi never to let Grandpa go out alone.

Grandpa's side. Grandpa is seventy-five and has looked after himself and his house since his wife died ten years ago. He resents being treated like a baby. He plays brilliant chess and remembers famous games, which makes Ravi wonder how he can forget people's names. When he sets out to fetch the Tamil newspaper, he guesses Ravi's instructions and walks out in his bright-yellow cap with his eagle-headed walking stick.

The chase and its humour. Ravi decides to follow him. He hides behind an elephant-shaped bush, where a child asks if he is playing hide and seek and the child's mother threatens him with an umbrella. He hides behind a banyan tree at the tea stall, watching Grandpa enjoy sugary tea, bananas and ice cream, all forbidden at home. When Grandpa enters a barber shop though he is bald, Ravi ducks into the next shop, a ladies' salon, and is thrown out. Finally he follows the yellow cap onto a bus and finds a stranger: Grandpa had given his cap to the man at the barber shop.

Kinds of irony. (1) Situational irony: the "watcher" is the one who is fooled. (2) The title irony: the memory vitamin is meant for Grandpa but is needed by the mother. (3) The detective book Grandpa gives at the end has tips on avoiding being fooled while trailing a suspect, which mocks Ravi's failed trailing.

Role reversal. The grandchild plays guardian and the grandfather plays the one who must be watched, but it is Grandpa who is in control. The roles of the adult and the child are also reversed, since the mother forgets and the "forgetful" old man remembers.

Tone. The tone is light, comic and warm. The humour makes a serious point about respect.

Central idea. The elderly deserve respect and independence, not condescension.
