Hi! I am so excited about cmaping!
Me too! What are you most excited about?
Cooking over the fire. How about you? 
I also like a fire, but maybe as a more social activity as well.
I could see that. So you like to have fun with friends? 
I do, and I think that the firewood would help me do that. But I can also see that you'd like to have some.
 🙂 I was hoping for some extra food because I am horrible at cooking- worried I might burn some.
Well, I'm a little less worried about the food myself - I think that there's going to be enough in the basic supplies.
How do you feel about the water? I'm not to concerned about it.
I'd like to have some to make sure that I can do washing without worrying about a drinking supply.
I would be ok with one water, two food and two firewood.
Could I trade a firewood for food - so you get three food & one firewood?
Sure. That would sound good and we each get a water.
I think that's a good deal, so I'll go ahead and submit it.
