answer: #Person1# borrows CDs from #Person2# for the school dance because inviting a band is not affordable. #Person2# promises to give them back in perfect condition; otherwise, his class will buy the damaged ones.
documents: #Person1#: Can I borrow your CDs for our school dance? 
  #Person2#: Oh, you don't ask much, do you? 
  #Person1#: I promise I will personally guard every single one and they will come back in perfect condition. 
  #Person2#: I'll tell you what. Your class can rent them from me for the night and buy back any damaged ones. 
  #Person1#: That sounds fair. That's still cheaper than paying a band to come play for us. 
  #Person2#: Not as fun though. A live band is way more exciting! 
  #Person1#: Our class doesn't have enough money. We already checked into it. 
  #Person2#: Let me know with your next dance. I know a band that may give you a break for the publicity.
