Hi, i am excited for the camping trip this weekend, how about you?
hello i am also pretty excited, doing fairly well but my water leaked and messed up a lot of my supplies
Dang, that sucks. I assume water is a pretty high priority for you then?
Yes. I a more then willing to trade you for some of yours. If you could maybe spare 3 bottles of water I can give you 3 food
I will take that offer, if i get two firewoods as well.
kind of a lot, I can give you 1 firewood and 3 food for the 3 water. what do you need or are low on?
I would like water as well, i am going to a desert, so i will need extra water. I propose i take 1 water 1 firewood, and 3 food.
I would be okay if you can add another water or firewood, your choice and then I can agree to that 
So i assume that water is highest priority for you, and food is of lowest? That would mean if you got 2 highs (water) and 2 mediums (firewood) you would get a value of 1.47. If i tatke 1 high ( water) 1 medium (fire) and 3 lows (food) i would get a value of 1.47 as well. It would be fairly equal.
I can accept 2 water, 2 firewood and you receive 1 firewood, 1 water, and the 3 food
