Participant mturk_agent_2's preferences:
value2issue: Low: Water
Medium: Firewood
High: Food
value2reason: Low: I packed a lot of extra water with me, so there is very little chance I would run out.
Medium: The weather forecast changed at the last minute, so I need to have some more firewood, just in case.
High: I forgot to grab one of the coolers before leaving my house, so I need some more food.

Negotiation dialogue:
mturk_agent_1: Hi! Would you be able to spare some food?  I have more people coming on my camping trip than I expected.

mturk_agent_2: I actually forgot one of my coolers at home, so I am a bit low on food, too. I could spare some water if you could spare some food.

mturk_agent_1: I could give you 2 packages of water if you could give me 2 packages of food 🙂

mturk_agent_2: Hmmm, that is tempting, but I don't really need water. I would have trouble sparing food, but I might be able to spare 1 package for a couple packages of firewood. 🙂

mturk_agent_1: So you would give me 1 package of food for 2 packages of firewood?

mturk_agent_2: I think I could do that. If you give me the 2 packages of firewood, I might need some extra water to put out my fire the next day, though, so could I have 2 packages of water, also?

mturk_agent_1: So you want 2 packages of everything?  That won't leave me with enough supplies.

mturk_agent_2: I think that the food is quite valuable, though, that is why I am willing to give 1 package in exchange for 2 firewoods and 2 waters. Do you have something else in mind? 🙂

mturk_agent_1: I'm not sure I understand what you are proposing...can you clarify?

mturk_agent_2: I mean that I am okay with you having 2 packages of food, if I can have 2 packages of firewood and 2 packages of water.
