Participant mturk_agent_2's preferences:
value2issue: Low: Firewood
Medium: Food
High: Water
value2reason: Low: I know that the weather report has predicted that it will not be unseasonably cold at the lake.  Most of the food I brought does not require a campfire.  Cold spaghetti and pizza are fine with me. 
Medium: Exercising outdoors all day certainly can zap your energy. Having extra nutrition on hand would be very beneficial. 
High: Summer days at the lake can get very humid and hot.  I want to stay hydrated so I can explore all around the lake. 

Negotiation dialogue:
mturk_agent_1: Hello, excited for the camping trip?

mturk_agent_2: Oh yes.  I have been looking forward to this trip for a while.  How are you?

mturk_agent_1: Alright, just trying to plan everything! 🙂

mturk_agent_2: I know. I really don't want to forget something I will need.  Have done that in the past.

mturk_agent_1: Me as well.. What are you biggest concerns? I am afraid to run out of water as I dehydrate a lot and start feeling sick. I can go longer without food but water is crucial. 

mturk_agent_2: I agree water is crucial.  How about if I take 2 waters and give you 2 food and 2 firewood.  I usually bring food that doesn't need a lot of cooking so firewood is not a priority for me.  It's only me and my son so I know we'll have enough food. 

mturk_agent_1: I was hoping to get 3 waters. But I could do 2 waters - as I mentioned - I start feeling sick and dehydrated but food I do not consume that much and skip my meals a lot. Firewood would not be needed for food for me but more for keeping warm and having light when it is dark..

mturk_agent_2: I think I can give you 2 waters as you mentioned your dehydration condition.  I know from a family member that some people get dehydrated much faster than others. If you could give me 1 water, 2 food and 2 firewood, I think we can have a deal. I will try and find a natural source of water and boil it on the fire for safety before drinking.Does this deal work for you?  

mturk_agent_1: What about if I give you 1 water, 3 food and 1 firewood?

mturk_agent_2: One water will work. As I'm thinking about my choices, extra food with my teenage son may be just what we need to avoid meltdown.  I accept your offer.
