value2reason: Low: Having enough firewood can keep you warm if it gets too cold. You need firewood to start a fire.
Medium: You don't want to run out of food on a camping trip. You want to have plenty just in case something goes wrong outside. 
High: Plenty of water can prevent dehydration. It is always wise to drink plenty of water in the great outdoors.

Negotiation dialogue:
mturk_agent_2: Hi there. How's it going?

mturk_agent_1: I am doing good, how are you doing?

mturk_agent_2: Doing well. My kids are looking forward to this camping trip. They've never done it before so they're looking forward to the experience!

mturk_agent_1: Yes, camping trips can be quite fun. I am sure it will be a plesant experience for them.

mturk_agent_2: Yah we have a few things planned. One of the things they are looking forward to is reading scary stories by the campfire and making s'mores

mturk_agent_1: That sounds like a lot of fun. What do you think you will need for that experience?

mturk_agent_2: We likely need a lot of firewood and some water to put out the fire when we are done lol. What are you thinking?

mturk_agent_1: Yea, I'm not too into firewood because it will be quite hot when I make my camping trip. I could definitely use some more food just in case of an emergency out there.

mturk_agent_2: Then how about I give you all my food in exchange for all the firewood and since I have to put out the fire, maybe 2 water for me and 1 for you?

mturk_agent_1: That sounds like a fair deal. I have no problem with that one.

mturk_agent_2: Submit-Deal

mturk_agent_1: Accept-Deal
