Hey there!
Hi! How are you?! You excited for your camping trip??! I sure am ready to go on mine!
I am very excited, I'm actually going camping in a week. I drink a lot of water so it's important that I bring a lot. What about you?
I really am! I have been watching the weather and updates about the area I will be traveling to.  They are experiencing a severe drought, so I will be in need of some extra water as well! I planned on staying an extra couple days as well.  There is a stream nearby I believe, but I'm not sure how much it has dried up.
That's good to hear, you always have to be careful with wild water though, it has all kind of germs. Sounds like you'll have plenty of dry firewood though. 
Yes, I would be willing to let you have all the firewood for 2 of the cases of water.  How much food were you needing?
I like your water and firewood arrangement. Can I have 2 of the food since you're getting 2 of the water? 
Let me think on that. I know there won't be much for berries or small animals to hunt for.  Is where you are going have much available for you to hunt and scavenge for?
It might but with the summer season hunting isn't exactly legal at the moment. I tend to camp in remote areas so going to the store for more food isn't really an option. I've already let you have extra water so I don't think it's too far of a stretch to let me have some extra food.
Okay, I can let you have 2 of the food then.  I do appreciate your generosity on the extra water.
