M: Hi, I heard you’re looking for a different apartment.
W: Yeah, the place I’m in is really bad.
M: It was OK when I was there.
W: (4) Oh, the boiler keeps breaking and when it does, we lose the heat for several days at the time.
M: Why doesn’t the owner replace it?
W: (5) Well, she said it’s cheaper to keep fixing it. She’s a nice enough person, but she just doesn’t want to spend the money. In any case, I’m sick of being cold.
M: Can you get your deposit back if you move?
W: (6) If I give two-month notice, I can get the whole thing back.
M: So what kind of place are you looking for?
W: I think I’ll try to get into one of those tall buildings near the university there’s nothing really special but at least they are new and comfortable.
M: I heard of those buildings are pretty noisy. The walls are thin and you can hear everything that’s going on in the other apartment.
W: Oh, that’s terrible. I need some place quiet to finish my paper. I guess I’ll have to look at some more ads. Maybe new isn’t necessarily better.
M: Why don’t you try some of those apartments in Winsor? They’re supposed to be nice.
W: Oh, aren’t they expensive?
M: Not really, you’ll be surprised at how reasonable some of them are. (7) The problem there is that the bus doesn’t run that way.
W: That will definitely be a problem. I can’t afford a car right now. I guess I’d better check a few of the places here in the city before I make a decision.
