W: Did you have a good time last weekend?
M: Yes, I did. I visited some friends in Pennsylvania. They live in a small town called Canonsburg.
W: That must have been interesting. I’ve never been in a small town — just big cities.
M: Neither had I.
W: What did you do?
M: There isn’t as much to do as there is here. No plays or concerts. People make their own entertainment, though.
W: What do you mean?
M: Well, on Saturday we went to a potluck supper.
W: A potluck supper? What’s that?
M: The whole neighbourhood has a party. Everybody brings something. It’s all put on the table and you can eat whatever you like. That is a potluck supper.
W: It’s something like a picnic, isn’t it?
M: Well, yes. The weather was warm, so we had this one outdoors. But in winter they have them indoors, too.
W: What else did you do?
M: On Sunday we went for a drive. We had lunch at a drive-in.
W: Is the countryside interesting?
M: Beautiful farmland. You’d like it.
W: I’m sure I would.
M: On Sunday evening some people came to dinner. It was very informal — we just sat around and talked. Just a nice Sunday night supper.
W: That’s the kind of evening I like. I don’t care for a formal dinner so much.
M: Neither do I.
