value2issue: Low: Water
Medium: Firewood
High: Food
value2reason: Low: Plenty of water can get water from a nearby well
Medium: We have some pieces but would prefer more in order to have a longer-lasting fire to enjoy at night and to keep bears away
High: Highly underpreapred for this trip and failed to recognize how poorly I would be at finding food

Negotiation dialogue:
mturk_agent_1: Hello, I would like negotiate with you for some supplies for a camping trip

mturk_agent_2: What do you have in mind, I could use some things myself

mturk_agent_1: We have most basic necessities but could use some more firewood, food and water.

mturk_agent_2: We have some of that, but would like to know which you need the most?

mturk_agent_1: We are taking our small child camping with us for the first time, and are thinking we would need the most firewood to help keep them warm.   

mturk_agent_2: I would be willing to give up a little firewood and some water if you can give me as much food as possible. I vastly underestimated how much food I would need

mturk_agent_1: I do believe that would be possible.  

mturk_agent_2: Thanks, is there a preference on how much firewood you need?

mturk_agent_1: 3 packages would be ideal, but I can certainly work with what you are willing to share.  Is there a certain amount of food you need?

mturk_agent_2: Same situation as you, please make a trade offer and I will accept if it is fair to both parties
