value2issue: Low: Water
Medium: Food
High: Firewood
value2reason: Low: It can be risky to not have water on hand because humans need it so much and so frequently.
Medium: It's easy to underestimate how much food you need, and it's much bettter to have extra food than to be hungry.
High: It can be very helpful to have extra firewood in case your fire goes out, or so you can help someone else build a fire.

Participant mturk_agent_2's preferences:
value2issue: Low: Food
Medium: Firewood
High: Water
value2reason: Low: The food initially given to us is good. A few extra snacks would be good in the case of picky eaters or if some food gets ruined. 
Medium: Extra firewood would be helpful to make sure the campfire is lit all night
High: It is very hot here in the summer so we will need extra water

Negotiation dialogue:
mturk_agent_1: Hi, I'm hoping we can come to a nice deal. 🙂 I'm most interested in firewood, because it always helps to have extra if your fire goes out.

mturk_agent_2: That makes sense. I'm also interested in firewood, but have a great need for water due to the current weather. 

mturk_agent_1: That makes sense. How about we start out with I get 3 firewood, and you get 3 waters?

mturk_agent_2: Great idea, that works for me. 🙂

mturk_agent_1: Okay, let's do that, and then split the food. Since there are only 3, do you want to flip a coin to see who gets 2 of those?

mturk_agent_2: That sounds fair, how much food do you feel you need? 

mturk_agent_1: I would prefer 2 because it's really easy to underestimate how much I could need.

mturk_agent_2: That's fine, I'll take 1. I think I have enough with what was originally given. 

mturk_agent_1: Sounds good! So I get 3 firewood, 2 food, 0 water; you get 0 firewood, 1 food, 3 water?

mturk_agent_2: That's sounds right. Thanks 🙂

mturk_agent_1: Cool, I
