Hello
Hello! How are you doing today?
I am doing great
Great! For our camping trip, I would love to take all the water and firewood. You can have all the food. 
I really need the firewood,  It gets very very cold at night where I go camping.
I really needed firewood also.  I have brought my whole family camping which includes my 2 and 3 year old.  They really need to stay warm
I am just going to walk away,  I can't have my family freeze
I do not want my family to freeze either but walking away doesn't benefit either of us. How about I take the water and 2 firewoods, you have the rest
No deal, I need at least 2 firewood
Ok, I can agree to 2 firewood but I will have to take all the food and water to compensate
I am walking away, completely unfair
You haven't offered anything and walking away means you get nothing so that doesn't seem like an option
You can have ALL the water, and 1 firewood
If you want two firewoods, i will need some of the food.  My family maybe cold, we can't be cold and hungry.  I need at least 1 food
