Daniel: When I grow up, I want to be an astronaut.
Me: Good for you. Do you know what you need to be an astronaut?
Daniel (doubtfully): A space ship?
Me: Well, yes, but do you know what you need to do now so that you can be an astronaut when you grow up?
Daniel: Buy a space suit?
Me: Mmm, no, I meant work very hard at your maths.
Daniel: Like what’s 1+1?
Me: Exactly.
Him: Only harder than 1+1. That’s very easy.
Me: Yes, that’s right.
Him: Maybe as hard as 8+5? That’s a very hard one, even I don’t know that.
I think I have given him the impression that astronauts are examined on their tables before they are let into a space ship.
