Example output: No
Example explanation: Both participants do not agree to the deal, so the answer is No.
Q: THEM: i'd like to have the two hats and book  YOU: how about you can have the two hats and one ball, i keep the books and 1 ball... right down the middle.  THEM: not much for sports, balls don't do much for me.  YOU: well, they do not help me at all, so i'd prefer we meet down the middle somehow. do you propose anything different?  THEM: alright, i'll take two hats and the two balls if they don't do a thing for you.  YOU: and we're still going to roll with an uneven split. in that case, i'll take the books and a hat, then?  THEM: yes sir.

Yes
