Negotiation dialogue:
mturk_agent_2: Hello.  I would like to offer you 2 food and 2 firewood.

mturk_agent_1: Hello. That's a nice offer. I definitely need some food, but I need water more than I need firewood. I only need 1 firewood.

mturk_agent_2: Ok.  I will take 2 firewood then. I definitely need water too. So how about you get 1 water, 2 food, and 1 wood.?  

mturk_agent_1: Would you mind telling me what you need the water for?

mturk_agent_2: Yes, I have a friend that will be visiting but I really only brought enough for myself 

mturk_agent_1: Oh of course. As for me, it's going to be dangerously hot here, and I just need to have some extra water so we don't get heat exhaustion.

mturk_agent_2: I know food is a need, but what if I give you another food?  So you would get 1 water, 3 food?  Then I would get 2 water and 3 firewood?

mturk_agent_1: I can agree to that. That sounds fair to me, if that sounds fair to you?

mturk_agent_2: Yes.  I think we have a deal.  I get 2 water, 3 wood.  You get 1 water, 3 food. 

mturk_agent_1: Perfect. Feel free to enter in the deal. I hope you have a good camping trip.
