value2reason: Low: I can gather firewood on my own if I really need to.
Medium: I fell in a huge muddy puddle and would like to wash myself off, but since I'm camping, I can deal a little better with it.
High: My family wants to stay one more night and we didn't bring enough food for extra nights.

Negotiation dialogue:
mturk_agent_2: Hello, I would like to have three packages of food. We've decided to stay an extra night but need more food to do so.

mturk_agent_1: I would be open to that if you could give me three packages of water 🙂

mturk_agent_2: Hmmm...I'm pretty muddy due to clumsiness, so I may need one extra. I could give you two waters and all of the firewood. What do you think? 🙂

mturk_agent_1: So are you suggesting that I would get 2 waters, 3 firewood, and no food?

mturk_agent_2: Right! Well, beyond the food you already have. 

mturk_agent_1: I have an extra person camping with us that I didn't expect when I bought food, so I could use one if you're willing 🙂

mturk_agent_2: I understand that! I wasn't expecting to stay an extra night, but the weather is too perfect to leave. I can manage with two packages of food for sure. 🙂

mturk_agent_1: Great!  Thank you for being so understanding!

mturk_agent_2: No problem! So are we in agreement that I get 2 food, 1 water and you get the reverse? I could also probably use one firewood, but it's not as important to me.

mturk_agent_1: I can give you one firewood, so I'll be getting 1 food, 2 water, and 2 firewood?
