Ana wants to be a veterinarian when she grows up. She wants to work with guard toads and battle toads, who sustain many injuries in their line of work. She would rather switch careers than work with bookworms (they are abominable).
Ali wants to be Papa when she grows up. Upon graduation into life, she will promptly grow a beard and become a guitar ninja.

Mama: 'So kid, what do you want to be when you grow up?'
Ali: 'I don't know.'
Aside from a lack of grey hair and a profound disinterest in the Financial Times, this new answer may mean that she has already grown up. I reckon the typical age cycle of the question goes about like this:
Q: 'So, what do you want to be when you grow up?'
Grown-up: 'No clue. Better-rested?'
