Hello, excited for the camping trip?
Oh yes.  I have been looking forward to this trip for a while.  How are you?
Alright, just trying to plan everything! 🙂
I know. I really don't want to forget something I will need.  Have done that in the past.
Me as well.. What are you biggest concerns? I am afraid to run out of water as I dehydrate a lot and start feeling sick. I can go longer without food but water is crucial. 
I agree water is crucial.  How about if I take 2 waters and give you 2 food and 2 firewood.  I usually bring food that doesn't need a lot of cooking so firewood is not a priority for me.  It's only me and my son so I know we'll have enough food. 
I was hoping to get 3 waters. But I could do 2 waters - as I mentioned - I start feeling sick and dehydrated but food I do not consume that much and skip my meals a lot. Firewood would not be needed for food for me but more for keeping warm and having light when it is dark..
I think I can give you 2 waters as you mentioned your dehydration condition.  I know from a family member that some people get dehydrated much faster than others. If you could give me 1 water, 2 food and 2 firewood, I think we can have a deal. I will try and find a natural source of water and boil it on the fire for safety before drinking.Does this deal work for you?  
What about if I give you 1 water, 3 food and 1 firewood?
One water will work. As I'm thinking about my choices, extra food with my teenage son may be just what we need to avoid meltdown.  I accept your offer.
