What is the woman’s suggestion?

M: I’m having trouble making ends meet. It looks like I have to make another phone call to my parents.
W: I don’t think it would be a problem if you cut down on the discs you buy.

M: You’ve spent too much time on doing course work, Sally. Don’t you think you should go out and get some fresh air?
W: Thanks for the advice. But this is how I relive my stress, I’d rather not get too far behind.
