Medium: Water
High: Firewood
value2reason: Low: Since I will be walking more than usual, additional food is required. 
Medium: Walking is the only way to and from the campsite, so I will need to be properly hydrated.
High: There is no firewood in the plains where I'll be camping, and temperatures are expected to be freezing.

Participant mturk_agent_2's preferences:
value2issue: Low: Firewood
Medium: Food
High: Water
value2reason: Low: I don't intend to cook with fire and I certainly don't need firewood for heat because I am always HOT!
Medium: I am just one person camping and the food would go a long way for just me.
High: I usually drink a lot of water on a regular basis.

Negotiation dialogue:
mturk_agent_2: Hi, I would like all of the water and 2 food packages. You can have all of the firewood and one food package. Does that sound good?

mturk_agent_1: Nice to meet you! I definitely like the idea of having all of the firewood, but water is very important to me. Let's see if we can come to and agreement on how to split up the water.

mturk_agent_2: I typically drink a lot of water every day. So I can't agree with much less on that!

mturk_agent_1: Alright, I'm sure we can something that works for both of us. The location I'm camping in is only accessible by foot, so I anticipate that I'll need a little more water than normal to feel completely safe. Is there any water source nearby your campsite?

mturk_agent_2: Nothing that I would trust. Additionally, I have a dog that will need water as well.

mturk_agent_1: Oh well that is something to consider. I love dogs. 🙂. I'd be willing to take less in that case, and let you have 2 of the waters. Would you be OK with leaving me with 1? I'd be willing to split the food up the same way (you get 2, I get 1).

mturk_agent_2: That works. I know water is important. I promise I won't be using it to water plants or wash clothes!

mturk_agent_1: 🙂 haha of course! I think we've come to a good agreement then! You get the 2 Waters, and I get Water. You get 2 Foods, and I get 1 Food. And I get the 3 Firewoods. Correct?

mturk_agent_2: That is perfect for me and my dog!  Yes!

mturk_agent_1: Perfect! I'll submit the deal shortly. What type of dog do you have?

mturk_agent_2: Submit-Deal

mturk_agent_1: Accept-Deal
