Hi! I am pretty excited to go camping this weekend, what about you?
I'm excited, too! I think it's going to be fun. But I see we have these items. What do you need most of?
Yes we do. I am going camping desert adjacent, so I need water.
Oh, that makes sense! I could give you all the water if you're willing to give me more of the other items. I could use food and firewood to help me stay nourished and warm.
That sounds fine, if i can have 3 waters, i will just take one of either food or firewood. 
Would you do 3 waters and 1 firewood and I get 3 food and 2 firewood? I feel like that's pretty fair.
Yes, that is fine by me, i am going by myself, so the food is not very important anyway. 
I'm glad we could come to a deal. You were easy to negotiate with! We'll both have enough for our camping trip.
Me too! Hope the weather holds up.
Likewise! We could use it!
