Negotiation dialogue:
mturk_agent_2: I need all three of the firewood and three water.  You can have all the food.

mturk_agent_1: 😮 May I ask why? I do need food, but I need some firewood as well.

mturk_agent_2: I need firewood to cook the fish I plan to catch.  I don't really need more food, but I can use a little water too, since it's warm.

mturk_agent_1: I need firewood, because I have a medical condition that causes my veins to close if I get too cold at night. I don't mind sharing the water.

mturk_agent_2: Can you get by with one firewood?  If I give it up, I'll need some food, since I won't have enough to cook all the fish.

mturk_agent_1: I could give you 1 firewood, 2 waters, and 1 food. 

mturk_agent_2: If you make it two food, we have a deal.

mturk_agent_1: I would rather let you have the third water than other food. I don't like fish. ☹️

mturk_agent_2: Okay, you can have two firewood and and two food, I'll take the rest.

mturk_agent_1: Ok. That seems fair enough to me.

mturk_agent_2: Looks like we have a deal!
