Why did the man borrow the woman’s computer last time?

W: Did you have a busy week?
M: Emm, well, no. I mean I didn’t do a lot, but I bought a computer.
W: You did? Thank godness. Now you don’t need to borrow mine. You had it for two weeks last time.
M: Yeah, so sorry about that. I wrote my history paper on it. Thanks again, by the way.
W: Sure, no problem. So how do you like your computer?
M: Oh, it’ s really cool. I use it everyday.
W: Really? Are you using it for class? I mean you’re working on the paper now, right?
M: Emm, yeah, yeah, but I don’t use it for class.
W: So what do you use it for?
M: Emm, actually, I just watch DVDs on it all week.
