Why does Vivian call Roger?

M: Hello?
W: Hello, Roger.  This is Vivian.
M: Oh, hi Vivian. How are you doing? How’s your apartment working now?
W: Well, that’s what I’m calling about.  You see, I’ve decided to look for a new place.
M: Oh, what’s the problem with your place now? I thought you liked it.
W: Yes, I do. But it’s a little far from college, and the traffic is killing me. Do you think you can help? I thought you might know more about the housing situation around the school.
M: Okay. How much do you want to spend on a new apartment?
W: Uh, somewhere under 500 dollars a month.
M: And anything else?
W: I need one with furniture.
M: Well. I know there is an apartment near the south gate of the school that seems suitable. I’ll drop by after class today.
W: Okay, thanks a lot.
M: No problem.
