THEM: the ball and hats are the highest value for me. i would be willing to give you one hat and two books if you allow me to have a ball and a hat.  YOU: unfortunately, the ball has the highest value for me as well. let's see how we can do this.  THEM: in order to make up for losing the ball, i would need all of the other items. are you willing to do that?  YOU: i'd be willing to let you have both hats and one book. how's that?  THEM: i really need both hats and both books to break even.  YOU: i need at least a book w / the ball to break even, too.  THEM: i can't agree to that.  YOU: ok. i can't agree to anything else either. wouldn't be a good deal for me.
