Teacher: Now, understand the problem? Solve this instance: THEM: i'll take the books. you can have the rest.  YOU: ok, but just to avoid getting the system warning i'm going to pretend to disagree. i disagree!  THEM: ah ok. well then i disagree ; )  YOU: haha ok, so you just want the books? because that works for me.  THEM: yes  YOU: cool, it's a deal.
