value2reason: Low: If I'm tired from my other activities, I likely won't be up late throughout the night in order to need fires/firewood.
Medium: Water is very important so that I stay hydrated throughout the trip. 
High: I'll be very active on this camping trip, so I'll need to replenish calories.

High: Firewood
value2reason: Low: My campsite got ravaged by a bear yesterday while I was out on a hike. I don't think I have enough food to be comfortable for the rest of the trip. I need additional food packages to sustain myself for the next couple days. 
Medium: I am going on a hike during this trip, and I need extra water to be able to bring with me on the hike. I don't want to get dehydrated. I won't be able to bring the large gallons I have with me, so I am hoping to negotiate additional packages of these waters. 
High: Hello. I need additional packages of firewood because I forgot extra blankets and a sweatshirt at home. The fire will help keep me warm, and I need enough firewood to build a fire every night. 

Negotiation dialogue:
mturk_agent_2: I really need to be able to build a fire every night and I don't have enough firewood. I forgot to bring a blanket and a sweatshirt, and the nights are supposed to cool down a lot. 

mturk_agent_1: Hello! I have no issue with you taking a lot of the firewood - I likely wouldn't be outside much at night anyway. 

mturk_agent_2: 🙂 Cool thank you! What can I help you with? 

mturk_agent_1: I feel like I'd need the food the most. I plan on being very active throughout the trip, and if I'm not able to eat well, this wouldn't be possible.

mturk_agent_2: Okay. I can definitely spare you some of the food! Do you need any water?

mturk_agent_1: Yeah, water is important too... but I think it's a little less important than food for me. 

mturk_agent_2: Same with me. We can split the water. 

mturk_agent_1: I like that! If you took all the firewood, could I have two of the waters?

mturk_agent_2: Sure. That's ok with me. 

mturk_agent_1: Thanks for being reasonable. These are important decisions.

mturk_agent_2: 🙂

mturk_agent_1: So if I take two food, two water and no firewood, is that alright with you? 

mturk_agent_2: yes. it's a deal.
