Participant mturk_agent_1's preferences:
value2issue: Low: Firewood
Medium: Water
High: Food
value2reason: Low: We don't mind cold weather and I think there is no wild animals here. But it will be good to have camp fire. We can tell horror stories and roast marshmallow.
Medium: I have some water with me but might not be enough. We don't know if our camp site is near a river or not. 
High: I have 4 kids and they eat a lot of food. We need more to make sure this is going to be a good camping experience. I really don't want to hear them complaint all night. 

Participant mturk_agent_2's preferences:
value2issue: Low: Water
Medium: Firewood
High: Food
value2reason: Low: I know I can filter water, but I really would prefer if I could have bottled water. I really don't like the taste of river water.
Medium: I am pretty good at making fires so I could definitely use this firewood to build our next fire if we decide to go somewhere else.
High: My metabolism is very high so I eat a lot of food normally and I really struggle to function when I'm hungry. As long as I am well fed, I am very happy.

Negotiation dialogue:
mturk_agent_2: Hello. I hope you are doing well. So what items are you looking for?

mturk_agent_1: We are doing good. Hope you are well and healthy! I really need the food. I have 4 boys with me and they eat like an elephant!

mturk_agent_2: I understand that. I am very similar to your boys. I am always hungry no matter how much I eat. It's a curse, really. I don't know about you, but I can tell when I'm hungry because I feel lightheaded and weak.

mturk_agent_1: Yes. Couldn't agree more! Which item do you prefer most?

mturk_agent_2: I really would prefer food as well. I want to have the energy and ability to really enjoy this camping trip. How do you feel about firewood and food as well?

mturk_agent_1: I prefer water than firewood. I just don't like going to the river to get water. besides, I think our campsite is far from the river. How about you?

mturk_agent_2: I don't mind filtering water even though it doesn't always taste great. I do like firewood so I can cook some actual meals instead of having to eat granola bars the whole time. I love the feeling of a nice fire, too.

mturk_agent_1: Firewood is nice and We can roast marshmallow. The boys will like it!

mturk_agent_2: So how do you think we should split this? We both want food, but I think I really like firewood and you really like water.

mturk_agent_1: I am Ok with 1 food and 3 water. how about that? 

mturk_agent_2: So I would get 2 food and 3 firewood? I like that deal.

mturk_agent_1: If it is possible, can you give me 1 firewood? Just so we can make smores.. The kids will be really grateful! 🙂

mturk_agent_2: I can do that if I could have a water, just at least to get me through the night.

mturk_agent_1: well, I really prefer water. And you already have more food...

mturk_agent_2: True but I gladly offered all of the water to you. You at least still get 1 food.

mturk_agent_1: Ok. maybe I'll come to your camp to roast the marshmallow then. You got a deal.

mturk_agent_2: You can come over any time you want! I'll even bring some camp chairs 🙂
