As far as supplies go, I think its going to be hot and sunny where I'm going, wouldn't mind a bunch of extra water.' 'Water is extremely important to me too.  I can give you 2 waters if you give me all 3 firewoods. '
Utterance: 'Hmm, ok, thats pretty fair. I do have a larger group going as well, so would it be okay if I got 2 extra food then?'

Yes
