What are they discussing about?

M: What would you like to do this Sunday?
W: I’m not sure. Have you got any ideas?
M: I’d really like to play football with some friends. What do you think of that?
W: There’s nothing I like less than football.
M: I’m sorry you feel that way.
W: But I’m fond of climbing mountains. We could climb mountains.
M: I’m afraid I don’t care for climbing mountains.
W: OK. What else do you enjoy doing?
M: I’m crazy about music. We could get together and sing with the guitar.
W: That’s all right. I guess.
M: You don’t sound very enthusiastic.
W: I can’t sing well, so I avoid singing.
M: Hey! Why don’t we have a picnic?
W: That’s a good idea! I like to go out on picnics.
M: Let’s have it in the forest.
W: Oh, I don’t like the forest, a bit too cold.
M: I enjoy sunny countryside. So let’s have it there.
W: That’s a terrific idea!
M: Having a picnic is a wonderful way to pass the time.
W: Then we are agreed?
M: Yes, Sunday at eight.
W: I’ll tell the others. I’m pleased.
