hi, what are your preferences?
Hi I prefer as much water as I can, some food, but I don't need any more firewood. What are your preferences?
I need as much food as possible. I could use a little water but I don't need any firewood either
I can give you 2 units of water if I can get 2 units of food?
I think that's fair
I am sorry about that. Reverse that. Can I get 2 units of water and give you 2 units of food?
Oh yes, I misread that as well. 2 food for me, 2 water for you
How do you want to split the firewood?
Can I take 2 of the 3? I need it a little, though not a lot. You mentioned not needing any. 
Could you tell me more about why you need 2 of the 3? I am open to giving you them, but I am not sure yet.
I think I'll need a little since I have a big group joining me. I'd like to be extra prepared.
I can give you 2. I don't have a huge group with me so I feel that is fair.
