M: Hello.
W: Hello, Sam. This is Paula Hanson. Sorry to bother you. But I’m having a small problem I thought you might be able to help me with.
M: Sure, Paula. What is up?
W: Well, you know Sarah and I moved into an off-campus apartment in the fall, over on the west side of town.
M: Yeah. What happened?
W: Well, the dishwasher broke down. So we reported it to Ms Connors, the owner, and she said she’d take care of it. But a month went by and nothing happened.
M: Did you get back in touch with her?
W: I got a repair person to give me an estimate, then I sent it to her. When I didn’t hear from her, I had the repair done. And I removed the cost from the rent cheque.
M: So what is the problem?
W: She called here as a mad cow. She said she could have gotten the repair done for less money. Now she’s threatening to drive us away for not paying the full rent.
M: Hold on, Paula. It does sound pretty serious. But I’m sure you can all sit down and work this out.
W: Well, you are over at the law school, so I wondered if you would mind coming with Sarah and me when we go to talk to Ms. Connors. We’re supposed to meet her tomorrow night at eight.
M: Sure. I haven’t studied a lot about contracts yet. But I’d be glad to help you straighten things out. Why don’t I stop by at about 17:30?
W: Thanks, Sam. You are a lifesaver.
