Hello, how are you?
I am good. How are you?
I am good also, I am getting ready to go camping and wanted to talk about extra firewood that I need.  I can give you 2 extra water and 1 extra food but I need 3 firewood packages.
I am sorry.Even i need 3 firewood packages.
I see, I just got over the flu and am afraid that I will get cold at night.  Thats why I need the 3 additional firewood packages.🙂
OK. I agree to the deal
Thats great, I can give you extra water and food, would that be good for you?
Extra water would be fine.
Great, I can give you 2 extra water and 1 extra food.  Can we make a deal now?
yes
