Medium: Firewood
High: Water
value2reason: Low: As a diabetic, it would be really dangerous for me to go low on food, so I usually need extra snacks available to me to make sure my blood sugar is high enough. 
Medium: I am camping in a part of the woods that has a lot of wild animals, and firewood is known to scare them away. Yet I still need enough firewood for my basic cooking needs. 
High: I have diabetes and need to make sure I have extra water available to take with my medication in case I go into shock or my blood sugar drops too low.

Negotiation dialogue:
mturk_agent_1: Hello, how are you doing today?

mturk_agent_2: Very good. How about you?

mturk_agent_1: I'm doing well. I'm looking forward to going on my camping trip but will need some additional items to make sure the trip is safe, healthy, and enjoyable. 

mturk_agent_2: Same here. 

mturk_agent_1: I have diabetes, so it is very important to me that I get extra packages of water and food. When I'm at home, I always need to pack extra drinks and snacks for myself in case I go into shock and need to take medication. The trip could be very dangerous for me if I don't have access to these additional supplies. 

mturk_agent_2: Actually mine own purposeful need is firewood and water. Being on a first time adventure, I lack these items as I was inadequately prepared.

mturk_agent_1: Okay, so firewood and water are your two most pressing needs?

mturk_agent_2: Yes.

mturk_agent_1: Okay. I'm willing to give in on the firewood, but I really can't give in on the water or the food. As a diabetic I have to put my health first. 

mturk_agent_2: I can give out the food in exchange for the firewood

mturk_agent_1: Okay. I need all of the water, if you're getting the firewood. 

mturk_agent_2: I can't give out all the water. I need to be hydrated as well. 

mturk_agent_1: You already have all the basics, though, so you won't lack sufficient water to be hydrated. I have a serious medical condition that requires that I have access to additional water. 

mturk_agent_2: The maximum bundle I can give is all packages of food + 1 package of water

mturk_agent_1: Sorry, that won't work for me. I've already said that I have a medical condition that requires additional water. You do not need that much water just to be hydrated -- you already have basic water. I can give you all of the firewood, but I need all of the water. 

mturk_agent_2: In that case I exchange all the water only for all your firewood

mturk_agent_1: I can give you all the firewood - but as a diabetic, I still need at least one extra package of food for my blood sugar levels. So, as my final offer I can give you all of the firewood, and two extra packages of food. Do you agree to these terms?

mturk_agent_2: No, I give out only one extra package of food

mturk_agent_1: I think you misunderstood what I said. I said that *you* would receive all of the firewood, and two extra packages of food. 

mturk_agent_2: ok

mturk_agent_1: Ok, great. It was nice negotiating with you.

mturk_agent_2: same here
