Participant mturk_agent_2's preferences:
value2issue: Low: Food
Medium: Firewood
High: Water
value2reason: Low: I can live without food longer than I can live without water or warmth. However, without food I will not have the energy I need to accomplish the things I want to accomplish while on my camping trip. 
Medium: Being able to boil water is essential for treating wounds if I sustain an injury. Also, cooking my food properly is very important as is keeping warm at night. 
High: I need additional water more than anything else because I can get firewood for myself from the forest. I can also survive longer without food than I can without water if an emergency should arise. 

Negotiation dialogue:
mturk_agent_2: I would like to give you more food and firewood so that I can have more of the water. I am someone who gets very thirsty very quickly. I'm also a bit bigger than a lot of people and I sweat more as a result. 🙂

mturk_agent_1: that is unfortunate, its quite hot here especially during the day, so I need all the water I can get

mturk_agent_2: I understand that and sympathize. It's very humid and hot here as well. Does it get cold at night there? If so, the firewood would be very beneficial to you. 

mturk_agent_1: its very cold at night, I can have all the wood and give you the food

mturk_agent_2: I would be okay with giving you two firewood but I need at least a little firewood for cooking and boiling water. 

mturk_agent_1: I will take two wood, and two water, how is that?

mturk_agent_2: No, I'm not interested in that because I really need the water. The food I'm okay with parting with more than the water. 

mturk_agent_1: I really need the water too.  its also my most valued item

mturk_agent_2: It's mine as well. Since you need more firewood than I do I would be willing to give you two firewood, one water and two food.

mturk_agent_1: in that case I can take three wood and one water to be fair

mturk_agent_2: I think if you're getting two firewood and two food that you are still making out better on this deal even if you only get one water.

mturk_agent_1: I have given up two of my most valuable items, you should be willing to sacrifice a little too, so its either I get three wood or two waters, and two foods

mturk_agent_2: I won't be cold at night like you will though so the firewood is more important to you than it is to me. I still need at least one firewood to cook with but I'm willing to give that up. I will give you three firewood, one water and two foods. 

mturk_agent_1: sounds fair
