Hi there! Are you excited about camping?
Hey! I sure am! The only thing is, I just learned that the canyon where I'm camping is going to be experiencing an unexpected heat wave over the next few days and I'm worried I might not be fully prepared. ☹️ What about you?
Same here! Last time my daughter got dehydrated and it made her sick!
That sounds awful! 😮 Where are you going to be camping?
In Arizona, so I know it'll be hot. How about you? 
Same! At least, I won't need firewood, because it will be so hot. I'm very worried about the water situation though. It's just going to be me out there and the only fresh water is at the base of the canyon, and that's a really long and dangerous hike down for one person.
Well, if you give me 2 firewood and 2 food I will take just one water and you can have 2. I don't want you getting hurt!
That could work, but if possible I would like a little more food then, in case I do need to hike to the stream on the last day. I only have a couple of traps with me and those can be unreliable for food. Would it be ok if I take 2 water, 2 food, and 1 firewood?
No, if I give up the water I would want 2 of the food because I have extra people coming one of the nights.
Oh, I didn't know you had more people on the way. I understand. If I have to stay up in the canyon, I might need to build a fire to keep coyotes away at night. Would my taking 2 water, 1 food, and 2 firewood work for you?
