Hi! I prefer to acquire firewood for cooking and water for hiking long trails.
Hello! I really need water myself--I didn't bring enough to go hiking, and it's going to be hotter than I planned for. And I really wanted to go on a long hike ☹️ How about this: I get all the water, and you can have all the firewood? I don't need firewood so much, really.
I really like hiking also, as i have a habit of running a lot. So i would give extra firewood and food for extra water.
Okay, how about this: you get all the firewood and one water, and I get two water?
For two water I will give all food and one firewood
No, thanks. I really need water a lot, and I don't want firewood all that much.
Okay, I like your previous deal! 
Cool! So, 3 firewood for you and 1 water, 2 water for me; how should we split the food?
I keep all food.
Okay, that doesn't work for me, because that means you get 7 items and I get 2.
Okay, well I'll give 1 food
Give me 2 food and we'll have a deal.
Again.3 food and 1 firewood for 2 water
If I don't get at least 4 items total, I'm walking.
Okay 2 water for 3 food and 2 firewood
How about I get 2 water and 2 food, you get 3 firewood and 2 food?
Fine. It's a dealllllll
Sweet! Thanks a lot 🙂
