Hello, how are you? 🙂
I'm good, how are you doing today?
I'm doing great!  I'm on the first camping trip with my five children.
Wow, that's amazing. My parents took me camping when I was young. Now we going hiking every other weekend. What do you plan on doing?
That sounds like so much fun!  I hope we get to hike some.  I have my four month old baby with us which is exciting.  I'm worried I didn't bring enough water for his bottles, though.
That sucks, you need to be hydrated. What supplies do you require? My family loves to grill, so we do require food.
Grilling is so much fun!  We left our grill at home so we can't really do that.  I will trade you some food for some water if you would like?
sure that sounds fair
Ok, do you have any interest in any fire wood?
I do need firewood, we cook over open flames. 😮How you get 2 water, 1 food and 1 firewood?
How about if I give you 3 food for 3 waters, and then we split the firewood?
I do require at least one water, hiking is very physical demanding. Also there are 3 firewoods?
yes there are 3 firewoods.  Okay I understand about the water.  then how about 2 foods for 2 waters, and we somehow divide the three firewoods? 🙂
Could I possibly get 2 firewoods? Assuming Water is your high value item?
Sure, we can do that
