value2reason: Low: I have food but I am not sure that I brought enough to last the entire time sadly. 
Medium: I recently just got over a cold and want to make sure to stay hydrated. 
High: The part I am camping at gets particularly cold at night and most of my food is things that require cooking. 

Negotiation dialogue:
mturk_agent_1: Hi, how are you, I'm really excited about my trip, how about you?

mturk_agent_2: I am excited as well 🙂! I can't wait to finally get some fresh air!

mturk_agent_1: Me too! Speaking of which, I'd really like to be able to have as long of a fire as possible, sing songs and stuff. I'd like all the extra firewood, I'd be okay with only one extra food and water.

mturk_agent_2: Oh, ironically I was going to ask the same. The site I camp at is very cold at night, not to mention all the food I brought requires cooking ☹️. Maybe since we both are in need of wood we can keep it, but I may require an extra water. I'd be willing to lend an extra ration of food for it however. 

mturk_agent_1: So I would get 3 firewood, no water and 2 food?

mturk_agent_2: My bad, I misspoke. I'm still getting over my cold so please forgive me. I am proposing this-I would get 2 firewood, 1 water and 1 food. You would get 1 firewood, 2 water and 2 food. How does that sound? 

mturk_agent_1: Sure, I am good with that deal.

mturk_agent_2: I am happy about that! I hope your trip goes great and you get much needed relaxation! 

mturk_agent_1: same to you

mturk_agent_2: I am sure I will have a great camping trip!
