Complaining 抱怨
It's a good idea to be as polite as possible even when complaining about something.

1. A: I wish you wouldn't play the TV so loud. 
    B: Sorry. Where you trying to sleep? 
    A: Yes, And while I think of it, please ask when you want to borrow my records. 
    B: I'm sorry. You're right. I should have asked.

2. A: Do you think you could keep the noise down? 
    B: I'm sorry. Am I keeping you awake? 
    A: Yes. And another thing, would you mind not making long distance calls. 
    B: I'm sorry. I thought you wouldn't mind.

3. A: That radio's pretty loud. Could you turn it down, please? 
    B: Sorry. Was I disturbing you? 
    A: Yes. And something else, please don't borrow my clothes without asking. 
    B: Sorry. I guess I wasn't thinking. I won't do it again.

4. A: You don't have to play that record so loud, do you? 
    B: I'm sorry. Has it been bothering you? 
    A: Yes. And please ask me the next time you want to use something. 
    B: I'm sorry. I meant to ask you.
