Peter: Helto. May I speak to Mary?
Peter : Mary, Freda and I were wondering if you and David would like to have a night out with us sometime.
Mary: All right, we'd like that very much. What did you have in mind?
Peter: Well, perhaps we could go and see a film, and then have something to eat afterwards.
Mary: That would be great. When?
Peter; We were thinking of Friday.
Mary; That should be OK. I'll have to check with David, but I don't think we are doing anything.
Peter; All right. Perhaps you could let me know tomorrow?
Mary; OK. Or I'll phone later. See you then! And thanks for the invitation.
Peter; Hello, 2045789.
Mary: Hello, Peter?
Peter; Yes. Is that Mary?
Mary: Yes. How are you?
Peter; Fine. Have you spoken to David?
Mary: Yes. I'm afraid we're busy on Friday. We're going to a party, apparently. What are you doing on Saturday?
Peter: Freda's parents are coming over.
Mary: Oh , that's a pity. Some other time then.
Peter; Yes. See you tomorrow then.
Mary : Yes, see you.
