Hello!  I am getting ready to go on a camping trip and will need some extra supplies.  Are you also going camping or hiking?
Yes I am going camping and hiking and would like to procure some additional provisions
Fantastic!  It's really cold where I'm going to be camping at night.  
Wow, hopefully you have the proper weight sleeping bag. I’m planning on doing a lot of hiking and it’s very warm where I’m going. It sounds like you need more firewood than I do. 
I could use 2 packages of firewood.  That would be great if you could spare it. I can make it up to you with some extra water or food.
I actually feel comfortable with allotting 2 firewood packages to you but I would like to secure 2 waters  because of all the physical  exertion from hiking and the ☀️ 
Thank you!  I more than happy to let you have the 2 waters.  You are probably going to get pretty hungry from all of that hiking.
Yes come to think of it, power bars are really helpful but I don’t want to seem greedy taking additional food
Ok.  Do you mind if I take 2 packages of food? That will give us something to do if it rains when I'm camping.
I’d rather give you more firewood quite honestly 
Ok.  How about you take the 2 packages of food then and we'll have a deal.
So I’m thinking you take all the firewood bc I am taking our sprinter camping van and then I’ll take two water and two food packages
You want me to take all 3 of the firewood?  That's mighty kind of you.  Sounds like we have a deal.
Yes,so how do we submit it?
