They'll have to come some other time. W: Then we won't be able to go to the theatre tomorrow. M: No, I am afraid we have to change all our plans. W: All right. David, when exactly are you leaving then? M: I am taking the 7 o'clock plane to Rome. W: Are you coming home before you go to the airport? M: I am afraid I can't. I am still having a talk with my boss here. W: What about your suitcase? M: I am afraid you'll have to pack it for me. W: And who is fetching it for you? M: You'll bring it, darling. W: Why me? M: Because you are coming with me. It's your birthday on Saturday and this trip is my birthday present for you. I'll meet you at the airport, three quarters before the flight. Don't forget anything and don't be late. See you later, darling. What was said before this conversation?

Please answer this: M: I know. I'm just finishing it now. W: He wanted to know if we'd done them together. I said no. What's yours on? It took me ages to do mine. M: Well, I was really lucky. I found this book all about the population in New Zealand cities. W: Is it good? M: Yes, it's a great book! I photocopied three chapters. There are some brilliant charts and... W: What are you going to do with all that? M: Well, now I'm going to copy these pages and these charts and then I'll finish my project! W: You're not supposed to just copy the book. M: Oh! I think Mr. Harper won't know. W: He will know! He asked us to write a list of all the books we'd used. Remember? That's not the point anyway. M: What is the point then? W: Well, the point is that you're supposed to write your own project--you can't copy someone else's writing. M: Er... er... Well, you're right. Thank you for your reminding me of that.
