Hi! The weather is supposed to be much colder than I expected, so I'm going to need some extra firewood.  Can you give me some?
ohh thta is somehow too much to ask because i am in need of that to thouh it is not my highest priority but i need it for cooking
I don't need all of it, maybe just 2?
ohhh that seems unfiar to me though☹️
Well, one of us is always going to get more of one particular supply.  I'm willing to give you the greater share of something else that you need.
okay i will have 3 foods and 1 firewood and 1 water
Would you be willing to share 1 food?  I'm going to need some.
that will bring down my resources a lot
Fine, I guess I'm okay with that ☹️
okay deal?
