I have little babies with me. I need a lot of water. Can you give me all the 3 water?
No. That will not be possible because i will need a lot of it too.
I can then give up 1 water and you take 2 of any of the remaining that you will choose.
If you give me one water then i will take all the food and 2 firewood.
That I will need to walk away friend
Why walk away when we can agree? You need to consider me too.
You are taking almost everything. I can offer you 1 water, 2 food and 1 firewood. It is fair.
It's not fair. That means you take most of almost everything. Can i take 3 food, 1 water and 1 firewood?
I also need food please
Okay then. What if i give you 1 food and you give me another water? I have a condition that requires a lot of water.
With water, I can not do with less than 2 water. then i can give you 2 food and 2 firewood. Is that not fair enough?
I think that will be better. Though water is my top priority.
Do we have a deal?
It seems you are not ready to give up any more water. 
No. I am fair. I have taken 2 water and 1 food and 1 firewood
Okay
