Why can’t they meet on Thursday?

M: I’d like to talk to you about our next building project. Can you fix a meeting for this week? What about Thursday?
W: Well, I’m sorry. I’ve been extremely busy this week. I’ll be at a meeting all day on Thursday. And I’m going out of town on Friday. Is Wednesday all right?

M: I enjoy camping out in the summer. A great change from city life, I think.
W: Yes, you said it. I went with my friends last Sunday. We really enjoyed ourselves, and we are going camping next weekend. Would you like to come along with us?
M: I’d love to, thank you.
