Medium: Food
High: Water
value2reason: Low: I don't get cold easily. I already have my blanket and sleeping bag to keep me warm.
Medium: I need more food packages because I lift a lot of weights. I need to eat a lot of protein to keep up with my daily caloric needs.
High: I need additional water because I have a condition where I get dehydrated easily.

Negotiation dialogue:
mturk_agent_2: Hello there. I

mturk_agent_1: Hello!

mturk_agent_2: I'm interested in making a deal with you on the packages.

mturk_agent_1: I think that I have some opinions about what might work best for me and be fair for us both. What is the most important to you out of the three items available?

mturk_agent_2: I need water the most. What do you prefer?

mturk_agent_1: Water is also important to me, but I think that a large amount of firewood and food could also benefit me as well.

mturk_agent_2: I see. I don't need firewood that much. Would you like to take all of it so I can get more of the food and water?

mturk_agent_1: I would still need a bit of food, but yes the firewood would help me

mturk_agent_2: 🙂 Great! Take all the firewood then. Then I'll take a greater share of the food and water.

mturk_agent_1: No, I will still need more food. 

mturk_agent_2: You drive a hard bargain. 😮
