What will the woman do on Friday?

M: Would you like to go to the movies with Lois and me on Friday?
W: I wish I could, but I’m having dinner at my brother’s.
M: It’s OK. We could find another time.

M: Uh-uh. Look! I’m going to be a little late for class.
W: You do need to hurry up!
M: I hope Prof. Clark doesn’t start on time today.
W: Are you kidding? You can set your watch by the start of his class.
