Hi. Water is very important to me. 
Hello, I don't really need water
What is it that you need?
I need food and firewood
I need water and then firewood
You can have all the water if I can have all the extra food
OK, but first tell me why you need extra food
I have 10 people in my group
I see. I need more water because I came across some people who were lost and they are very dehydrated.
I need 2 firewood because it gets below freezing at night
Oh I wouldn't want for you to freeze☹️ It also gets cold where I am, so I need 2 firewood as well.
IF I can't get 2 pieces of firewood, I will walk away
oh that is too bad. I feel the same way.😮
Sorry we could not come to a agreement, I am walking away
OK. I am sorry it has to come to this. I really need the firewood as much as you do to keep warm as it is very cold where I am for this time of the year.
