#Person2#: Oh good. Did you have a good weekend?
#Person1#: Yeah, it was good. I went to the cinema with some friends yesterday. What about you?
#Person2#: Not too bad. Hey actually I'm calling because it's my birthday this Saturday. I was wondering if you would come.
#Person1#: That sounds good. What time?
#Person2#: Is 7:00 o'clock OK? David won't finish work until 6:30.
#Person1#: Oh sorry I'm afraid I can't make it. Is 7:30 alright?
#Person2#: Sure. 7:30 then.
#Person1#: Do you want me to bring something like a cake or some drinks?
#Person2#: Oh no. I'll get the food and everything. Just come and help me celebrate.
#Person1#: Well, in that case, I'll invite you to a piano concert next Friday.
