What does the man imply about Mary?

W: Mary insists she’s coming to my graduation.
M: But she has to work that week, doesn’t she?

M: What do you think of my new painting? I’ve just finished it.
W: Well, the colors are a little strange, don’t you think? Perhaps a little too vivid, maybe?
M: Ah, yes. That’s the point. It’s called Colors.
W: Oh, yes, I see. Well, it’s not quite my cup of tea but then we all have different tastes, don’t we?
