input question: W: Don't you see the price keeps going down these days? I insist that we wait some time so that we can save more money. M: You have a point there, but it is inconvenient for me with this broken mobile. Sometimes it powers off by itself. It really makes me very angry when I am talking with someone. W: In that case,you'd better buy a new one. M: Well, I'll buy one this evening after supper. W: All right. M: Let's go to the shop together so that you can give me some advice.

input question: W: I still remember the painting course had so many people in it that you couldn't really get any personal help. M: Yes, but they have decided to limit the number this year, so if you want to do it you have to book a place. Anyway I wonder whether I ought to do computing really. W: But would it be advanced enough for you? M: I think so. The woman who runs it is supposed to be very good. She's not just a programmer. She's a well-trained teacher as well. W: It's up to you of course. But at the end of a day's work, I just want something relaxing. And I'd have to pay for materials. I can't afford more than the minimum. M: Then why don't you try Spanish? And it'd be really useful on holiday. W: Don't the language courses last two terms? M: I don't think so. What was said before this conversation????
output answer: M: Hi, Tracy. I went into the college today to find out about evening classes.

input question: M: I used to. But I haven't played it for quite some time. I don't really have time these days with all my studies. Why do you ask? W: I'm trying to organize a group to play at some parties on weekends. We still need a guitar player. M: Well, I don't know. But your idea sounds fun to me. W: Oh, it will be. I'm more or less in charge of things, so if you want to give it a try, you're in. It's as easy as that. Besides, it's a great chance to get out to meet people. M: But I told you I haven't practiced for a long time. I don't know if I remember any songs I used to play. W: Don't worry about it. I just thought I'd ask you to try and join us sometime when we were practicing. We'll be practicing for a few months before we give performances. M: OK, I'll have a try. W: I'm sure you can do it. And it will be fun, too. What was said before this conversation????
