A: W: Hey! If you can't enjoy that at a sensible volume, please use earphones. I'm trying study.

Why don't you come by and take a look? M: Well, I'm not sure whether I can afford such a payment of 40,000 dollars at once. But I guess it won't hurt to see the house. If you can tell me how to get to your place from South Florida Street, my wife and I will be coming. What was said before this conversation?
