Hello there! I think we both are going after the extra stuff. I was wondering if I could get most/all of the firewood and maybe some of the water because I forgot to buy them. 
Well I really need the water because I've been sick(I won't go into details), but I'm a bit dehydrated.
Im sorry to hear that. That fine you can get the water if you need it. But is it fine that I get 3 firewood then?I really dont have any 
I need at least 1 firewood. I forgot to bring warm clothes unfortunately. How about I take 3 water 1 wood and all the food?
That is a little problematic for me because I did not bring enough also☹️. Maybe we can split this up a little more evenly?
Okay. I have a few hotdogs but I definitely need some chips or something to go with them. Maybe we can split the food up. But as for water I would like 2 at least. I don't think i can survive without it.
That sounds good. How about I get 2 firewood and you get 2 waters so we have some for both of us and maybe be let me have 2 foods cause I did not bring any and you already have some?
Sounds good except I could really use a bit more food. I'm trying to bulk you know? I would hate to waste my hard earned gains.
If thats the case I am willing to trade the leftover firewood you have for the one extra food. I mean the weather isn't suppose to be "that" cold any ways. 
Okay you can have 1 water 2 wood and 2 food. I'll just lose my gains I suppose ☹️. Sound good?
