Hi, I didn't bring any food with me and the area I am going to does not have many resources. Can I all of the food packages? 
I would at least like 2 of the foods. I could give you two. I forgot some of our food at home
Alright, if I can have two of the food packages you can take two of the waters. 
Oh i'm sorry i meant i will give you 2 foods and i get 1
Can I have two of the firewood so I can boil water? 
 I can give you 3 of the firewood, if i can have all 3 of the water
That sounds like a deal. Can you repeat everything you are taking so we can make sure we are on the same page? 
I get 1 food an you get 2, i get 3 waters and you get 0, I get 0 firewood and you get 3. Is this correct?
Yes that looks great 🙂
So we have a eal?
