High: Water is the most important thing to have around if something goes wrong and you get stranded.

Negotiation dialogue:
mturk_agent_1: Hi! I'm most interested in getting water. What are you looking for?

mturk_agent_2: Hello, could you tell me why water is your most interest?

mturk_agent_1: If something goes wrong on the camping trip and I get stranded, it seems by far the most useful thing to have around.

mturk_agent_2: I understand. I have a need for water too along with firewood. 

mturk_agent_1: Okay me too. Is there any reason you would need more food?

mturk_agent_2: I don't need more food, I have a specific diet I must follow so I bought plenty of food. I would like 2 water and 2 firewood. What do you think about that?

mturk_agent_1: That doesn't seem like a great deal to me because I'm left with only 1 water and 1 firewood. What if you get 2 water, 1 firewood, and 1 food; I get 1 water, 2 firewood, 2 food?

mturk_agent_2: Ok, I can see how it does not seem like a great deal. Your counteroffer works for me 🙂

mturk_agent_1: Okay! I will put in the offer and then you can accept. Everybody happy? 🙂

mturk_agent_2: Yes, everyone is happy 🙂
