Hey there, how's it going?
It's going good! Just making the final plans for my camping trip this weekend. What about you?
Yeah same here. The kids are really looking forward to it.
Same, my kids are as well! They have not been camping before. They are super excited about the campfires. I'm worried I don't have near enough firewood though. I just found out you can't cut any trees down where we are staying. 
oh no I'm so sorry to hear that. My kid are looking forward to the ghost stories around the campfire.
My kids will enjoy that as well. I'm hoping I can pack several extra things of firewood. If I could get 3 more packages I would feel better about having enough firewood to have campfires during the evening and to cook on. 
ok I completely understand. I am more than happy to offer you 3 firewood in exchange for 3 food. If you are ok with splitting 2 water for me and 1 for you that works well. My kids need food and water for their medications.
Hmm I will consider it. I'm worried about not having enough food for my kids. They seem to be on a growing spurt and get very frustrated quickly when they are hungry. I would be will to negotiate it I can get 3 firewood, 1 food, and 1 water. 
Food is very important to me probably as much as firewood is to you. If we can stick with the 3 food, 0 firewood and 2 water that would be great. 
I can tell that this is very important to your kids, so I will be willing to do this.
