Hello, fellow camper.  Are you ready for our trip?
Yeah
i plan on taking my children hiking.  So, I'm going to need plenty of food and water.
I'm so excited about this trip. It's the first trip I'm going with my family. I would need enough Food and firewood. 
I won't need much firewood.  How about I take 2 food, 3 water, and 1 firewood.
That isn't cool by me. I need the food as well. It's very important to me and my family. How about I take 2 food and 3 firewood. You can take all the water
You can have all the firewood, but I really would like 2 food.  My children are going to need plenty of energy if they are going to go hiking.
The food is important to me as well. Since you ain't ready to allow me take 2 food, you will have to sacrifice some water then. I take 1 food, 3 firewood and 2 water. You can take the 2 food and 1 water since you won't be needing any firewood
I would prefer taking 1 food, 3 water, and 0 firewood.
Okay then
