What can be the relationship between the man and the woman?

W: Hi, Bill, you look happy.
M: Yes, I’ve just seen a very funny film on TV.
W: What was it about?
M: It was about a careless man who got into trouble wherever he went. He couldn’t do anything right.
W: So you like it?
M: Yes, I do. It made me laugh a lot.
W: But I’d rather see something not only interesting but also instructive.
M: Oh, Jane, don’t be so serious. People sometimes need relaxation.
W: That’s true. But I just think that watching TV is not just for entertainment.
