What are the two speakers talking about?

M: What kind of dress are you looking for?
W: Since it’s getting warmer and warmer, I’d like something light. What do you think would be the best?

W: If you can do me a favor, maybe I could have my task done in an hour.
M: I would like, but Mrs. Hans asked me to type this paper this afternoon.
W: In that case I have to finish my work myself.
