Participant mturk_agent_2's preferences:
value2issue: Low: Food
Medium: Firewood
High: Water
value2reason: Low: I bought enough food and I would be willing to sacrifice for water or more firewood.
Medium: I would like more firewood because I think that it will be a big challenge for me to collect more during the trip.
High: I did not get extra water from home and I will need them during the trip to stay hydrated while exploring.

Negotiation dialogue:
mturk_agent_2: Hello, I think that I should get all of the water packages, 2 firewood and you can have all of the food.🙂

mturk_agent_1: Hi there, i appreciate your initial offer. 

mturk_agent_2: What is your offer on the additional packages?

mturk_agent_1: I would be willing to give you all of the firewood (3) and two of the water (2) while I get the rest

mturk_agent_2: Ok great, are you going to be ok with getting your own water and firewood during the trip?

mturk_agent_1: I think that I will be able to, so I'd like to offer you those extras.🙂

mturk_agent_2: Thank you, it would have been difficult for me to get more firewood and I appreciate the additional water. So I get 3 firewood, 2 water and 0 food.

mturk_agent_1: Yes, I think that deal will be the most helpful to both of us. I appreciate the food, which is important to me.

mturk_agent_2: You are welcome. Thank you for being so understanding, the extra packages are really going to come in handy for me!🙂

mturk_agent_1: Perfect, I will submit the deal after just a few more messages. You were great to work with!

mturk_agent_2: I agree and thanks, you also!
