W: Hello, Mary Smith here. Could I speak to Mr. Brown, please?
M: Speaking.
W: Oh, it’s you, Andrew, is it? I didn’t recognize your voice. Sounds as if you’re miles away.
M: Oh, hello, Mary. Yes, the line isn’t very good. I’ll speak a bit louder. Is that any better?
W: Yes, that’s much better now. Andrew, it looks as if I won’t be able to keep the appointment we made.
M: That was to be Friday, wasn’t it?
W: Yes, I’m so sorry. This visitor I was actually expecting last week had some kind of change in his schedule, and now he’s rung me up to say the only day he can come is next Friday.
M: I see.
W: And the trouble is, as he’s over from Argentina, I can’t very well put him off. Hope you understand.
M: Well, I suppose so.
W: But could we meet on Saturday? Or would you prefer the beginning of next week?
M: Afraid I’m tied up at the weekend. And...let me just check. Tuesday would be all right, I think.
W: Tuesday is O.K. for me too. Could you come here at 11:30 as we’d arranged? I’ll show you round our place, we could lunch together and work out the terms of our contract in the afternoon. How does that sound to you?
M: Yes, fine. I’ll write it down in my diary. That’s Tuesday, 12th December. Right, I’ll be at your place at 11:30 then.
W: Thanks, Andrew. Hope I haven’t messed up your arrangements too much.
M: Oh no, these things happen, don’t they? See you next Tuesday. And have a nice weekend.
W: Thanks. You too.
