Jake — Mum, Is it OK if I go to Shaun's house?
Mum — No, sorry, you can't.
Jake — I can't? Why not?
Mum — Because your grandparents are here this afternoon.
Jake — Oh, right. It is OK if I go this evening, then?
Mum — No, not this evening, Jake. You've got a lot of homework.
Jake — Well, can I go tomorrow?
Mum — Yes, you can.
Jake — Great, thanks.
