Hello! How are you?
Doing good, how about yourself
Doing well, just getting ready to go camping this weekend
Same here. I was hopping to get some extra water for the trip
I have some water! I am looking for food 
There's plenty of Food, and I don't really need extra, I'm on a diet. 
Oh that is great. I was wondering if you'd like to make a deal? I can trade 3 waters for 3 food? 
That could work, What do we do for firewood however? I was hopping to have a big fire tonight
I could give you 2 firewood
That would be wonderful
