Negotiation dialogue:
mturk_agent_1: Hi, how are you today?

mturk_agent_2: Good! How are you?

mturk_agent_1: I'm great! excited about camping :D

mturk_agent_2: I am too! Sadly I am not good at packing so im lacking some stuff

mturk_agent_1: Oh, what did you need the most? I personally don't like hunting or fishing, so I need food the most.

mturk_agent_2: Oh, haha. I m diabetic so I also need food the most, but if you are willing you can have most of the other stuff to trade off

mturk_agent_1: Alright, I'm willing to work with you. I don't want you going into shock and dying when camping. That'd be awful!

mturk_agent_2: Yea, I had that happened once. It was not fun. What else do you need so I can get a general idea of what you want

mturk_agent_1: I don't need firewood at all. I can find that anywhere. The water is my mid point. Go ahead and make an offer tho.

mturk_agent_2: Oh okay, how about this. ill get 2 foods and 3 firewood and none of the water. sounds good? 

mturk_agent_1: Okay, that sounds fine to me!
