Problem: W: Yes, Dr. Downs said he expects us to have the first five on the list. He is going to discuss them in detail. M: Are you going to buy them? W: I don't know. These books are expensive. And I don't have a lot of money on me. M: How about sharing them with me? W: Sounds good. M: Let's do this. I will buy three and you buy two of them. W: I would rather do it this way: we pay fifty-fifty for the books now. And at the end of the course you can take the books you find more interesting and I will take the ones I like. M: What if we both like the same books? W: Come on, we are not going to argue over that, are we? M: I was just joking. It's definitely a better idea. W: Then let's get the books as soon as possible.

Problem: Given the question: W: Oh, really? And are you going? M: I don't know. I used to hate school, so I don't feel like going back. W: But it's different now. M: Yes, I know. But it's still a difficult situation. You see, when I was at school I used to be bad at studies and none of the teachers liked me. W: Well; I think you should go. When I was younger, I used to dream about meeting a famous pop star. You can't let them down. M: Maybe you are right. OK, I'll go. What was said before this conversation?
