Dad: What’s that music?

Mum: It’s Tony. He’s playing the guitar.

Dad: He spends a lot of time playing the guitar. Has he done his homework?

Mum: Probably not. But all his friends are learning to play an instrument. He wants to play with them.

Dad: Hmm, I don’t want to stop him enjoying music, but he’s got to study as well. If he doesn’t work hard, he’ll fail his exams.

Mum: Let’s make a deal with him. We’ll pay for guitar lessons if he works hard at school.

Dad: OK, that’s a good idea.
