Participant mturk_agent_2's preferences:
value2issue: Low: Water
Medium: Firewood
High: Food
value2reason: Low: I'm hoping that even if I run out of water, I'll be able to find a running stream or other body of water that would allow me all the water I need
Medium: The firewood is already a pretty important item for camping, and is even more so if it gets cold at night.
High: My biggest worry would be having enough food in case an animal eats my food, or I were to get lost. 

Negotiation dialogue:
mturk_agent_1: Hi! How about I receive 3 food, 2 firewood, and 1 water?

mturk_agent_2: I can't do that. It would leave me with no food at all. How about I take 2 food, and 1 firewood, and 1 water?

mturk_agent_1: I really need more food than 1. I am worried about running out. I could take 2 food, and give you 1 food, 2 firewood, and 2 water.

mturk_agent_2: That is a very generous offer, which I very much appreciate. But I am also worried that I could run out. What if I take 2 foods, give you 2 firewoods, and 1 water?  

mturk_agent_1: Would you be willing to give me 1 food, 2 firewood, and 2 water?

mturk_agent_2: I could make that work 🙂 I'm sorry if I came off mean, I'm just trying to make sure I'll be ok. I don't camp often, so I'm not sure how to prepare.

mturk_agent_1: I understand. What are you using the extra food for?

mturk_agent_2: I brought some pre-packed snacks, and a few sandwiches. I'm hoping there are no hungry animals around. What about you?

mturk_agent_1: I was hoping to get some extra food for some picky eaters, but if they are hungry they will eat!

mturk_agent_2: Oh no! I know how picky eaters can be. I'm sorry to hear that. So are you thinking I'll give you the one food, and 2 firewoods, and 2 waters? Will that work for you?

mturk_agent_1: Yes, that works.

mturk_agent_2: Deal!
