THEM: hi, can i have the ball and the hats?  YOU: i'd like the ball and the books.  THEM: i really need the ball, how about one ball and one hat. it`s super fair on my side  YOU: that'd leave me at 5 and i usually don't make a deal for that low. if that's really the best you can do, i don't think we'll agree.  THEM: well, how about i just take the ball?  YOU: that would bring me to 6, which i don't love but will do.
