value2issue: Low: Firewood
Medium: Water
High: Food
value2reason: Low: Firewood could be useful, but since it's Summer I don't expect to need as much of this.
Medium: Given that I'm planning on being physically active, and it's Summer, extra water would be very useful. In fact, it will be necessary.
High: I'm going to be doing a lot of exploring and will be burning extra calories, so I'll need more food than I have.

Negotiation dialogue:
mturk_agent_1: :) Hey there, what are you planning to do on your trip?

mturk_agent_2: Hi, I was planning to go to the river. How about yourself?

mturk_agent_1: I'm going to be exploring the area around the site. I haven't been here before so it will be novel. What do you think the weather will be like?

mturk_agent_2: The weather is suppose to be very hot, that is why I am in need of the water 

mturk_agent_1: Yeah I can understand that. I also need water, but since I'm going to be moving around a lot, food is my highest concern. It sounds like neither one of us will be too concerned about firewood.

mturk_agent_2: I am wanting to build a fire, to be able to cook on. Since I will be on the river, I will have some water. What about If I had 2 of the firewood and the food. What if you have all the water and one food?

mturk_agent_1: Well, I'm glad you plan to build a fire! I don't, so I'd be willing to let you have all 3 firewood. I need some of the food as well. How about you take all 3 firewood, and I get 2 food and 3 water (you will have extra water, after all)?

mturk_agent_2: That is true. I would need some food, since I will not have any water. What if I have the 3 firewood and 2 food. That way you have the water so you will not be parched and you will have a food as well. 

mturk_agent_1: I think we're close to an agreement here! 🙂 Given that I plan to be very active, I'd still like to keep 2 of the food if I can. If I give up one water (who knows what you'll need, and the river won't be for drinking!), could we do a deal where I get 2 food and 2 water and you get all 3 firewood and 1 food and 1 water? Maybe you could catch some fish (if I do, I could share)?

mturk_agent_2: That is a great agreement! I would be happy with the 3 firewood, 1 food and one water. I hope we do catch alot of fish!🙂
