Kevin: Come on, Tim. Let's have a game. I have to go home soon. Tim: Why? It's only eight o'clock.
Kevin: My parents make me come home at nine. They don't let me stay out late on a weekday. Tim: Why not?
Polly: Because we've got school. My parents are the same. I am not allowed to stay out late on weekdays either.
Tim: Oh... good. What about going to a concert on Saturday?
Bob: Yeah. A friend of mine is performing in Green Theatre.
Polly: Really? What is he doing?
Tim: He is a puppeteer. His show starts at nine. Can you come?
Polly: Maybe. My parents don't usually let me go into town in the evening. Kevin: They may let you go. They let you go to the TV studio last week.
Polly: OK. I'll ask them.
