hello my friend i will like to suggest to you if i can get 2 food 1 firewood and 1 water.let me know what you think
Hello 🙂 We are camping in the desert near Joshua Tree NP. While your offer is fair, I am hoping to take three waters. I could give you another food package in return.🙂
okay but i will be needing water too i you give me 2 water 2 food and 1 firewood ?
Sorry that won't work. 🙂 I prefer your first offer to that one. My greatest need is water and firewood.  I can offer to give you the three food and 1 firewood.  That is better than your first offer, as far as I can tell. 
okay so i take 3 food 1 firewood 1 water while you take 3 water 2 firewood and 2 water.please is this okay by you?
Yes you can take three food and one firewood.  I need the water and firewood.  We will be doing a lot of hiking with a large group and it will be in the 90's with full sun.  We also need the firewood to keep warm as the desert gets cold at night.
okay can you spare 1 water for me as well while you take 2?
No, I can't spare it.  It is dangerous to hike in the anza-borrego desert without ample water.  There are no convenience stores or natural water sources to rely on either. 🙂
okay that is fine so i take 3 food 1 firewood while you take 2 firewood and 3 water .i hope we have come to a conclusion?
Yes, I am ready to finalize. You?
yes i am gals we could negotiate .i have agreed to the offer
