value2reason: Low: There is a fresh water stream nearby, if I run out of water I can always drink from the that.
Medium: A bear came to our campground and stole and ate all the remaining food. I need more food to survive the camping trip.
High: During the camping trip it is supposed to be unusually cold out. The extra firewood would allow me to keep warm at night.

value2reason: Low: I dont eat much so I dont really need extra food. The amount supplied will do just fine for me.
Medium: Whe hiking I tend to sweat a lot and can get dehydrated. I could use extra water to avoid getting ill.
High: I could use extra firewood to stay warm at night. I do not have a very good sleeping bag and I get cold easily.

Negotiation dialogue:
mturk_agent_2: Hi, it is nice to be going camping. I do not have a very good sleeping bag and I can get cold at night. It would be nice to have extra firewood. I dont eat much so I do not need much extra food. Would you be willing to give me two packages of firewood for a package of food?

mturk_agent_1: I enjoy camping as well. However, my campsite seems to be a bit chilly at night. I'd be willing to part with some firewood, yet I'd need quite a bit of food to compensate. I also have a stream nearby so water is plentiful if you need that as well.

mturk_agent_2: I may be able to do something with regards to food. Do you have enough water?

mturk_agent_1: I have more water than I need. How is your water supply?

mturk_agent_2: I could use some more water as I get dehydrated easily. Since you have enough, I could give you and extra package of food for your water.

mturk_agent_1: That sounds like a deal, what would you like to do as far as the firewood goes?

mturk_agent_2: I really need to keep warm with my not so good sleeping bag.☹️ I would be willing to do this. I get two packages of firewood and three packages of water and I will give you two packages of food and one package of firewood. You have plenty of water so you will not miss that.. 

mturk_agent_1: This sounds good to me, unless you would be able to part with three packages of food?

mturk_agent_2: No, I would like to keep one for me just in case I need it. If it sounds good to you can we finalize the agreement and move on. I think we have something that helps us both.🙂

mturk_agent_1: That works for me 🙂

mturk_agent_2: Great! Thank you
