Hello?
Hello, Bob? This is Nancy. I got the invitation yesterday.
Oh, can you come?
Yes, I think so, but Tony can't. He's got to go to his parents' and help them work on their house this weekend.
Oh, that's too bad.
Uh, Bob. I won't have any transportation that night. Think somebody could give me a ride?
Oh, sure! There's a group of people coming who live near you. I'm sure one of them would be glad to. If that doesn't work out, I'll drive you.
Great! Thanks, Bob. Uh, what will people be wearing?
Oh, you needn't dress up. It's a fairly casual party. We'll be in the yard, you know.
Good. I can wear my new pants and sweater. Uh, what can I bring?
Well, a side dish would be good. There'll be plenty to drink.
OK, see you then.
