Hello

Im running low on food☹️ are you willing to provide 1 food and i can offer you 1 water 
i can do that, can i have three water then
How about I give you 2 waters and you give me an additional firewood
you can have all the firewood if you offer me 3 water
hmm okay I can work with that so I'll give you 3 waters and I get 3 Firewood
sounds good!
so we can keep the food then
we should split the food i guess
hmm  how would we split it you get 1 and I get 1, how does that sound
