Hello, Lisa. I'm phoning to invite you to our house warming party this Saturday evening. We know you're very busy but we'd love you to come.
Yes, I'd love to. Well. I'll have a test next Monday and an article to hand in on Tuesday. Will the party go on very late?
Until 1:00 in the morning, but you don't have to stay that long. What about it?
Alright, I'll come. When does the party start?
At 8:00 o'clock.
OK, see you then.
