What do you have in mind?
I need additional packages of water, given that I get dehydrated fast.
I understand I have that issue as well. I will likly die on one  package . If i get two i will share it with you we can ration it 
This is something we will have to work on, how about we can share 2-1?
I will need 2 and give you one. I am willing to pass on the fire wood meaning. I get 2 packages of water and you get access to it an emergency.
In that case, I will need more of food.
that could work 2-1 for food; fire wood could be shared I know how to store it incase of rain and am a skilled out doors man. 
What are your thoughts on how to share firewood?
I am a skilled outdoorsmen If you let me hold all the firewood I would be able to perserve it. 
Appreciate it. But, it's not advisable to rely on skills, we never know what situation can we expect?
Thats true--But I am concerned about you if something happens to me you may not be able to utlise it. Maybe you could but I think we would both benfit if I held all the fire wood that way I could teach you some tricks.
That is so nice of you to be concerned of me. But, yes, I need to think of the food as well and would need firewood.
Yeah I agree that you could hold the food 2-1 that way there is a system of checks and balances.
Hmm..this is between thinking of the present and future. My reasoning is concerning the present.
agreed but like you never know what situation we can expect. you control the food and have intrest and acess to the water with me holding the firewood 
No, that would be unfair to you..My suggestion is to we will either decide on water or Food and firewood. Like 2-1 of the former and 1-2 of the latter.
