value2issue: Low: Water
Medium: Food
High: Firewood
value2reason: Low: Water is needed, but there will also be some of it in the rivers and streams where we are staying nearby. 
Medium: More food is needed because our camping trip will last about a week.  We need to ensure there is enough food so that we do not starve.
High: I need more firewood to ensure warmth at night and so that we have adequate fuel to cook our fish and meat with. 

Negotiation dialogue:
mturk_agent_2: Hi, I need lots of firewood and food - is water important to you?

mturk_agent_1: Hey, how are you?  Food is important to me, but so is water.

mturk_agent_2: I'm good.  Hope all is well and safe with you as well.  Yes, firewood is important to me because I need it to cook the fish and meat that we brought on the trip.

mturk_agent_1: I understand, that makes sense! I can let you have more, or most firewood.  I need some amount of both food and water though.  We don’t have enough of either.  ☹️

mturk_agent_2: Sounds good.  I can let you have more of or the most water.

mturk_agent_1: That seems like a good deal.  I can probably get by with just 1 food if i can have 3 water.

mturk_agent_2: Sure.  Would I be able to have 3 firewoods?

mturk_agent_1: Could i have 1 firewood so we can be warm at night?

mturk_agent_2: Sure.  That works.  So I get 2 firewoods, 2 foods, 1 water?

mturk_agent_1: Hmmm, i thought i got 1 food, 1 wood and 3 water 😮

mturk_agent_2: Oh ok.  That works too

mturk_agent_1: Great, i’ll propose it
