Hello, which item do you prefer the most?
Hi, I prefer food.  I have to eat many times a day because of the meds I am on.  
I need water the most as I need to be hydrated while camping, what is your second preference?
I agree about the water, but I would prefer firewood cuz I get cold easily. ☹️
How do you think we should split them?
I would prefer at least two food and two firewood and maybe one water?  What about you?
I would be okay with 3 water and 1 firewood
Okay, that sounds fair, so I get 3 food and 2 firewood?
Unless you have another offer
No I am good with that.   Thank you.
