I will submit a deal that might benefit us both.  
We can work on that together
What is on your most needed item?
I need Food, what is yours?
I kinda need water because I get dry mouth very often.  so without water it will make it hard to achieve getting other items in the wilderness.
Ok thats nice, I need food more because I didn't bring much and that a problem,  What do you think if I give you 2 wood and you give me 2 food?
🙂 Well let me counter it, more beneficial to both of us, you will get 1 water, 2 food and 2 firewood as I can easily find firewood in the forest.  The water due to my dry mouth illness, I need the most ☹️
Oh yes excuse me, I got confused, if you need water for me it's okay to give you the water you need.
Okay so my offer is good for you and me? 🙂
, Yes, I agree with that offer.🙂
