answer: #Person1# wants to borrow some books but #Person2# tells #Person1# #Person1# can't borrow more than 10 books at a time and explains.
documents: #Person1#: Excuse me, I'd like to borrow these books.
  #Person2#: I'm sorry, but we can only lend you 10 books at a time.
  #Person1#: 10? I thought it was unlimited.
  #Person2#: The rules have changed. Some students were taking out all the books for one topic and not returning them. That would give them a disadvantage over the other students in their class.
  #Person1#: Really? I can't imagine who would do such a thing. I guess I should put some of these books back. Sorry about the extra work.
  #Person2#: It shouldn't be a problem. They look like they're all from the same shelf.
