Why didn’t the gift go to the movies?

M: Do you want to see a film tonight?
W: I can’t. I have to review my lessons.

W: Yes. We’ re having our mid term test.
M: I wish you good luck.
W :Thanks a lot. But I’m a little nervous.
M: Nervous? You used to study very well.
W: But I haven’t studied for a long time.
