value2reason: Low: I'm not sure how much food I would actually need and I would hate to starve. 
Medium: I came on this camping trip because I want to really exercise the stress in my life away, but I am afraid of dehydration.
High: I have low blood pressure and I am frequently cold. I would need more firewood than most to stay comfortable on my trip. 

Negotiation dialogue:
mturk_agent_1: I get to go camping this weekend. 🙂

mturk_agent_2: Awesome! I do too! 🙂 I'm excited but kind of nervous too!

mturk_agent_1: Don't be nervous. What can go wrong?

mturk_agent_2: Well, I haven't gone camping in a number of years, and unfortunately my health has declined a bit. This might actually be my last trip for a while, and I'm afraid of something going wrong. 

mturk_agent_1: I'm headed to the mountains. How about you?

mturk_agent_2: It's in Upstate New York, near a gorgeous lake. I like it because it's secluded and very peaceful. 

mturk_agent_1: Sounds good. I'll be doing quite of a bit of cooking over an open fire during my trip.

mturk_agent_2: Wow. That sounds great! There's nothing like campfire cooking on a chilly night! I'll doing a lot of that too, but I also want to enjoy swimming as much as I can🙂 

mturk_agent_1: understood, I can give you 1 firewood, 2 food, and 2 water to make your trip better.

mturk_agent_2: Hm. I''ll definitely take you up on the water, thanks for that. The thing is, I have low blood pressure, and I have trouble regulating my body temperature so I am frequently cold. How about if I take two firewood, and the two waters. It sounds like you are going to do a lot of cooking, so you can take two of the food.  

mturk_agent_1: Will you take two firewood, 1 food, and 1 water?

mturk_agent_2: I don't want to take too much food, I want you to be able to enjoy all the cooking you are going to do🙂! But I would like two waters--I'd be afraid of dehydrating on my trip. I'd even throw in the extra food! that would give you all three! you could really do some cooking then!
