hello
Hello, there. Should we discuss how to divide up the items for the camping trip?
yeah. i need 2 firewood, 1 water and 1 food
I need to have 2 or 3 pieces of firewood because I did not pack any way to heat up my food without firewood.
I also need 2 pieces of firewood
That's unfortunate. I cannot agree to a deal without 2 pieces of firewood. I would have to walk away, but that would bee worse for both of us.
okay fine. will you give additional water?
Yes, that would work out. 
because i have some firewood with myself. i required 1 firewood, 2 water and 1 food
I would agree to this deal then.
