Given the question "Why is the man late?" and the answer "The maths class lasted longer than it should.", write a conversation that might have happened.
M: Oh, hi, Fred! I didn't know whether to save you a place or not. Why are you so late?M: It's our maths teacher. She always keeps us in class until ten past ten.W: Doesn't she know that you're supposed to get out at ten?M: I guess so. But she never looks at her watch. She just keeps talking.W: Don't the students complain about it? I would say something.M: No. Everybody is too polite.W: Well, you could try and talk to her.M: Maybe. But I'm afraid she might feel hurt.W: Well,it all depends on how and when you say it. If you tell her about it in a friendly way when she's not busy, she might be thankful. She might even ask you to remind her of the time in the future.M: Really? That would be wonderful. Thanks for your advice.
