value2reason: Low: Clean water is an important resource and something you cannot go without for long. 
Medium: I don't know how to start a fire without firewood. 
High: I am not an outdoorsy person. I would have a hard time identifying and finding food on my own.

value2issue: Low: Water
Medium: Firewood
High: Food
value2reason: Low: I enjoy hiking a great deal and water is an essential item to hike at my best.
Medium: It is supposed to be a very cold evening and firewood would be helpful to stay warm.
High: I didn't have a chance to eat before, so would like to have some food packages so I am not hungry during the trip.

Negotiation dialogue:
mturk_agent_2: What are you most interested in getting?

mturk_agent_1: I think food is my highest priority, What about you?

mturk_agent_2: Food is also my highest priority, but firewood is also pretty close for me.

mturk_agent_1: Would you be willing to take more firewood for less food?

mturk_agent_2: Yes I think that sounds fair.

mturk_agent_1: So if I take 2 foods and 1 firewood, you take 1 food and 2 firewood. What would be fair for water?

mturk_agent_2: What if I take two waters and you take one water then?

mturk_agent_1: I think that sounds fair, since you compromised on food. Sounds like a deal!

mturk_agent_2: I'm glad we could come to a compromise 🙂

mturk_agent_1: Me too 🙂 Thanks for making it easy and pleasant.
