Input: Consider Input: Context: 'how about I give you 2 waters and 1 food package in exchange for all your firewood?' 'I'm afraid that will not work for me. I have hypothyroidism, so I am intolerant to cold temperatures. I was also planning on taking a swim in the river. I would prefer to take two firewood & one food package, & you may have the three waters, two food packages, & one firewood.' 'I'm afraid I also have need of the firewood. I have anaemia so i get cold easily so I need to make sure I have adequate firewood or i may freeze at night. I also have a thin clothing so they wont provide adequate warmth. How about all of my water and 2 food for all of the firewood?'
Utterance: 'Seeing as we both have a medical-necessity for the firewood, it's rather unfair that either one of us take ALL of the firewood. I felt that I was being rather generous with my previous offer.'


Output: No
