M: Hello.
W: Hello, Sam. This is Emma Robert. Sorry to bother you, but I’m having a small problem and I think you might be able to help me out.
M: My pleasure, Emma. What’s up?
W: Well, you know, Julia and I moved into an off-campus apartment last year. We’ve been happy with it until the past couple of months.
M: Yeah? What happened?
W: Well, the washing machine broke down, so we reported it to Ms. Hansen, the owner. She said she’d take care of it, but a month went by and nothing happened.
M: Did you get in touch with her again?
W: I got a repairman to give me an estimate and I sent it to Ms. Hansen. I had the repair done before hearing from her. And I deducted the cost from the rent check.
M: So what’s the problem?
W: She called madly. She said she could have gotten the repair done with less money. Now she’s threatening to expel us for not paying the full rent.
M: Hold on, Emma. It does sound pretty serious, but I’m sure you can all sit down and work this out.
W: Well, you’re studying at the law school, so I wondered if you would mind coming with Julia and me when we go to talk to Ms. Hansen. We’re supposed to meet her at 7：00 tomorrow night.
M: Sure, I haven’t studied a lot about contracts yet, but I’d be glad to help you straighten things out. I’ll stop by around 6:30.
W: That’s great. Thanks, Sam.
