Hi, my friend. My 6 children and I need more food, water and firewood tonight. I hope you understand and would let us have it. Thanks a lot.
Hello, I need some items as well for our trip.
Do you have any priority what you would like the most?
Well I was hoping to get mostly some extra food for the trip. What are you looking to get?
We are really hungry because we don't have food for a while so food is the most priority for us as well.
okay, well what else were you hopping to get? I'm interested in some extra firewood as well, I've got plenty of water though
Well, we could share you two of firewood and one of food. Is it alright?
That could work, If I take 2 Food and 2 Firewood, you can have all the water.
Alright, we will share you two food and two firewood, we will have one food, one firewood and three water. 
Sounds like a deal
