Kirsty: Hi Elaine. It's Kirsty, here.

Elaine: Hello, how are you?

Kirsty: Fine. Listen, I know this is very short notice but (do) are you doing anything tonight?

Elaine: Nothing why?

Kirsty: Well I  (take) my class to the theatre, but one of them can't go. Would you like to come?

Elaine: I'd love to. What's the play about?

Kirsty: Oh, I  (tell) you all about that a little later. I  (pick) you up at 6.30 — is that okay?

Elaine: Yes, OK. Or how about meeting a bit earlier? We could have a coffee beforehand.

Kirsty: Well, I  (see) the school principal at four, but I suppose I could come after that. My meeting (probably / finish) at about 5.30. Is that okay?

Elaine: Yes, of course. What time does the play actually start?

Kirsty: At 7.30, although we  (need) to be there before as I  (meet) my students at the theatre at seven. Afterwards they  (probably / want) to talk about the play for a little while. But I hope that (not / go on) for too long. There (be) plenty of time for us to discuss it at tomorrow's lesson.

Elaine: That's fine. I (see) you at 5.30!
