Negotiation dialogue:
mturk_agent_1: Hello! i wanted to see if you can spare some water, most of mine leaked out!

mturk_agent_2: Hi!  I can spare 1 package of water...it's hotter out than I thought, so I need more than anticipated.

mturk_agent_1: do you have anything you are low on and maybe we can work something out? I really need 2 and would be willing to offer something else

mturk_agent_2: I'm running low on food, and could use any extra that you are willing to spare 🙂

mturk_agent_1: if you can give me 2 water i can offer you 3 food

mturk_agent_2: Great!  How about firewood?

mturk_agent_1: i may be able to spare 1 fire wood if you only take 2 food instead of 3

mturk_agent_2: Since it's so hot out, I don't need as much firewood.  Food is the bigger priority.

mturk_agent_1: okay . So you can trade 2 waters for 3 of my food?

mturk_agent_2: So you would be getting 2 waters, 0 food, and 3 firewood?

mturk_agent_1: i would receive 2 water and you would receive 3 food
