Hi there! 🙂
Hello! I'm very excited for this upcoming camping trip!! 🙂
I am as well! I see we have some extra supplies. What are you most in need of?
I really could use the extra water. I have two big dogs that are coming along on the trip. How about you?
Water would be nice, but I would feel bad taking water from dogs. I guess I could use firewood and food if you need the water.
Okay, thanks! How much food would you like? 
Well, I could use a combination of firewood and food to make up for missing water. Maybe all the firewood and two food and you get all water and one food?
I would be fine with giving you all of the firewood if I get all of the water. I was really hoping to get two of the foods because I wanted to have a small birthday celebration for my husband. :) 
If you get all the water, you would be at an advantage with all the higher valued items. I would ask that I'm compensated for giving the higher value items by getting more items overall.
Okay, I guess that's fair. 🙂
