hello how are you?
Hi- I am doing great. I am really excited about my upcoming camping trip and appreciate your willingness to split some packages!
Me too! I checked the weather and it is going to cold. I'm looking for some more firewood and food. What are you looking for?
I plan on doing a lot of hiking and outdoor activities so my priority is the water and food.  Would you be interested if I took 3 packages of water, 2 food and 1 firewood?
Well, considering there at 9 items, I'd like to make a trade that is 5 and 4. How about we trade Me: 3 fire wood, 2 food  and 0 water and you: 0 firewood, 1 food and 3 water? 
Sounds like a reasonable offer.  What activities are you planning during your camping trip and how will each of your items be used?
My family is coming with me and we like to stay up late and talk, so I need enough firewood to last us long into the night. We are also making some special foods for a celebration. What will you be doing? 
We plan on doing a lot of hiking/visiting local landmarks. I definitely need water to stay hydrated while we are out and about, but we could definitely get food in town or if needed.  We plan on going to bed early and waking up early and not spending a lot of time around the campfire in the evening. Based on our plans, I will accept your offer of 3 water and 1 food. 
sounds like a great idea. I'm glad we could come to an agreement
Great! Glad we could work it out! 🙂
