Hello how are you?
Hello! I am doing well. How about you?
I'm doing well. I'm trying to prepare for this camping trip. 
Me too.🙂
What are you looking for?
Firewood. I need 3. What do you need?
I'm looking for mostly water and food. I have some firewood, but I don't think I could trade all 3. 
Ok. COuld I have all 3 if I gave you 3 food and 2 water?
Would you do 3 water and 2 food? 
Sure, that would work for me
