The teacher asked her class what each wanted to become when they grew up. A chorus of responses came from all over the room.
'A football player,'
'A doctor,'
'An astronaut,'
'The president,'
'A bus conductor,'
'A teacher,'
'A race car driver.'

Everyone that is, except Mannu.

The teacher noticed he was sitting there quiet and still. So she said to him, 'Mannu, what do you want to be when you grow up?'

'Possible' Mannu replied.

'Possible?' asked the teacher.

'Yes,' Mannu said. 'My mom is always telling me I'm impossible. So when I get to be big, I want to be possible.'
