Hello.  I am very interested in the firewood and would be very willing to forfeit all the water.
oh really.  i am willing to make a negotiation with you on that for sure.  where are you plannign to camp?
I'm camping near a natural spring and will have all the water I need.  How are you planning to eat?
i have some spare cans but i am not too worried about it.  its a low prioirty for me 
How about your water?  Won't you be going through a lot of water where you are going?
i am good on that,  i dont think i will be but its second on my to do list
Are you willing to take 1 firewood and 2 waters?  I also don't need the food.
yeah for sure.  sounds liek a godo trade to me honestly
Great!  Sounds like a deal.  Enjoy your camping trip!
you too thanks
