I forgot to bring any water, can I take two of them? 
What will you be using for? Would I be able to have two packages of food and 1 package of firewood?
I get heat stroke and faint easily, so I need to stay hydrated. You can have two packages of food, I have enough already. 
Great. Sounds like a deal. What about the firewood so I can make a fire. I can boil my water from river to use to cook and clean.
You can take one package of firewood to make the water and I can take two so I can cook the food I brought? 🙂
Thank you. That will be very helpful to be able to cook. I think we are all set. I will give you the 2 packages of water, you get 2 of the firewood and you get 1 package of food.
That sounds like a deal! 
Great. Are you good to submit the deal?
Yes everything looks good. Thanks for being understanding. 
Great..thank you for helping.
