Holly: So what have you decided about your birthday party, Max?
Max: Not much, Holly. To be honest, I haven’t thought about it at all.
Holly: Well, it’s getting close, so you need to send out the invitations soon. By this Friday,
really, to give people time to reply.
Max: I don’t really know who to invite. My schoolfriends, of course, and Mark, Jack and
Sean.
Holly: And Tilly and her sister.
Max: Yes. And Alicia. I hope she’ll be there. But I’d prefer not to have a huge number of
guests.
Holly: Twenty?
Max: Not that many, if possible. It’s only a small flat, and I only really want my close
friends there anyway.
Holly: I can understand that.
Max: Even so, some of them won’t know each other. My friends from round here aren’t
the same kind of people as the ones from school. They like different things, really. Holly: Well, that should make the party more fun!
Max: Maybe, but it`ll make it harder to choose music that everyone likes. I’ll have to go
down to the supermarket and buy some different kinds of music, to keep everyone happy.
Holly: If I were you, I’d make my own CD. You’ve got some great music on your
computer, and you could put lots of different things on it.
Max: That’s true. Though not everyone will want to dance, or listen to music all the time.
Maybe I should put a DVD on in another room?
Holly: Not if it’s just any old movie. That would be like watching TV at home.
Max: No, I was thinking of getting a new film that most people haven’t seen yet.
Holly: That’s a good idea! There are sure to be some who’ll want to watch it.
Max: Right.
Holly: So the only thing left to decide, I think, is which day to have the party.
Max: It’s got to be a weekend, so not the Thursday. Saturday would be best, I think.
Holly: I agree the weekend’s best, but the problem is that lots of people will be away on
the Saturday. Perhaps you should have it on the Friday?
Max: I don’t know.
Holly: I don’t think Alicia can come on the Saturday.
Max: All right, then. I’ll have it the day before.
Holly: I thought you might.
