[originaltext]M: I really can’t stand them anymore!W: Who? What happened?M: (

M: I really can’t stand them anymore!
W: Who? What happened?
M: (19) My roommates. Two of them keep talking till midnight and make it impossible to get to sleep.
W: I know how you feel. It’s never easy to live with inconsiderate roommates. I once had a roommate who never cleaned the dormitory or fetched water.
M: So what did you do with her?
W: At first I tried to ignore it because I didn’t want to cause anything unpleasant. But things didn’t become any better. Suddenly one day I broke out, and said something like " My dear fellow, I really appreciate it if you remember to clean the room once in a while. "
M: Oh, no. (20) You’ve got to be careful with complaints, especially when it comes to your roommates. Anyway you meet each other every day.
W: (20) That’s what I’ve learned from our quarrel and the subsequent coldness between us. Now I realize that I should have put it nicely or casually, something like "Hi, Cindy, it’s your turn to clean the dormitory today. "
M: Perfect. It’s hard to take offense at something like this. (21) Maybe we should learn tolerance and understanding.
W: (21)That’s right. We should bear in mind that we all have shortcomings, or rather peculiar habits. When I come to think of Cindy, she’s really a nice girl except being forgetful and careless.
M: I guess you are right. What would you do if you have roommates chatting at bedtime every night?
W: I would talk it over with them, of course. But I would remember I breathe noisily in my sleep and often keep them awake half the night as well.
M: You do?
W: No, just an example.
