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?

W: Well, this must be the National Library.
M: I guess so. Oh no! I don’ t think it’ s open today. Look. It says "Closed Tuesdays".
W: Well, we’ll just have to come back tomorrow.
M: But we’re supposed to go on that tour tomorrow.
W: Oh, that’ s fight. I forgot all about it. How about the day after tomorrow then?
M: It’ s OK with me.
