W: Hello, Sam. This is Paula Hanson. Sony to bother you, but I’m having a small problem I thought you might be able to help me with.
M: Sure, Paula. What’s up?
W: Well, you know Sarah and I moved into an off-campus apartment in the fall. The dishwasher broke down, so we reported it to Ms. Corners, the owner. 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 repairperson to give me an estimate, and then I sent it to her. When I didn’t hear from her, I had the repair done. And I deducted the cost from the rent check.
M: So what’s the problem?
W: She called here. Very Angry. She said she could have gotten the repair done for less money.[13] Now, she’s threatening to force us to leave 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’re over at the law school. So, I wondered if you would mind coming with Sarah and me when we go to talk with Ms. Corners. We’re supposed to meet with her tomorrow night at eight
M: Sure. I’ll be glad to help you straighten things out. Why don’t I stop by about 7:30?
W: Thanks, Sam. You are our lifesaver.
