M: How was your weekend?
W: It was awful.
M: Awful? Really? But I thought you were supposed to be going on a trip. Did it get cancelled?
W: No, unfortunately, it wouldn’t been better if it had.
M: What do you mean?
W: Well, five of us were supposed to go to Chicago in Lisa’s car.
M: Yeah?
W: And we were going to stay at Sue’s parents’ house, which is in Chicago.
M: Right?
W: So it’s about a four-hour trip, and we were going to get there on Friday evening, spend Saturday sightseeing, and come back last night so we could go to classes this morning.
M: OK. That sounds like a good plan. So what went wrong?
W: What didn’t go wrong? First of all, we were all crammed into Lisa’s tiny car with all four bags.
M: Sounds pretty uncomfortable.
W: Hold on. I’m just getting started. Remember how hot it was this weekend?
M: Yeah, It was so bad I had to get out of the library. I ended up going to the beach both days.
W: Well, we were stuck in Lisa’s car Friday afternoon and the air conditioner wasn’t working.
M: Why didn’t you open the windows?
W: We did, but the breezes blowing in weren’t exactly cool.
M: I’ll bet you were glad to get to Chicago.
W: That’s the worst part. We never made it. Mary started feeling sick from all the heat, so Lisa tried driving faster to find Mary something to drink. To make a 10ng story short, the car broke down and we were stranded till this morning in some small town near the Indiana border.
M: Couldn’t Sue’s parents come pick you up?
W: They were out of town.
