School Rules

Kate: Hi, Tom. How are you?

Tom: Hi, Kate. I'm fine, thanks. How about you?

Kate: I'm good. Do you know the school rules?

Tom: Yes, I do. We must be quiet in class.

Kate: And we mustn't eat in class.

Tom: That's right. We must raise our hand to speak.

Kate: Yes, and we mustn't be late.

Tom: Exactly. Well, see you later.

Kate: Bye, Tom.
