What are they talking about?

M: I enjoy camping out in the summer. A pleasant change from city life, I think.
W: Yes, you said it. I went with my husband last week.

W: Have you planned anything for the weekend?
M: Yes and no. I’d really like to go on a trip, but I don’t have any money. You can’t travel for nothing, you know.
W: I don’t want you to go away, John. I don’t feel like staying at school alone.
M: Well, in that case, I’ll be with you.
