What seems to be the man’ s problem?

W: What’s going on between you and Charlie? Did you have a fight or something?
M: No, but I can’t stand him anymore. He is the worst roommate I’ve ever had. He never cleans up after himself and he is always listening to loud music when I try to get some sleep.
W: Why don’t you have a heart-to-heart talk with him?
M: I’ve tried, but it didn’t work. Maybe you can talk to him. After all, you are his good friend.
