M: Well, you paid for the coffee when we were in that coffee shop. Remember? W: That's right. I remember feeling it to my pocket as we walked out. M: And then, we dropped in ... bookshop... W: Yes. But I remember taking a piece of paper out of my purse to write down the name of the book on it. I think I must have left the purse on the shelf. I'll call the bookshop and see if they found it.

input: Please answer the following: M: I play football, volleyball, tennis, and table tennis but volleyball is my favorite game as it's team game and you can play it with your friends, and enjoy it as a team. W: Is it quite a fast game as well? M: Yeah. It is a fast game and that's another reason why I enjoy it. W: How exciting... M: Yes. W: Where do you play, then? M: I play at local sports centres more during the winter and sort of play in tournaments around England. I also, in the summer, play beach volleyball. W: Is beach volleyball different from the volleyball you play in the centres? M: Yes, it's a very different game. Instead of six players on a team, it's only two players. W: You mentioned you played in tournaments--now do you do quite well in the tournaments? M: Yes, I've played for South West England and we've got through to the semi-finals of different England tournaments, and for Wessex, my other volleyball team, we've actually won a few tournaments. So yes, I have done quite well. W: Oh well done! What was said before this conversation?
