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.
