Negotiation dialogue:
mturk_agent_1: Hello, I would like to take all of the firewood and two of the water packages. You can take all of the food and the other water package. 

mturk_agent_2: I am not a fan of that deal

mturk_agent_1: That's alright. Do you have anything you need in particular? 

mturk_agent_2: I need food and water

mturk_agent_1: I need water too. One of mine has a leak.☹️

mturk_agent_2: the temperature is 115 degrees F where I go,  If I don't have extra water I will not make it

mturk_agent_1: That sounds awful 😮. Would you settle for you taking two of the water packages and leaving me one?

mturk_agent_2: I guess if I can have 2 food and you can have 2 firewood

mturk_agent_1: Some of my firewood is wet (and basically useless unless it dries in time). So how about 3 firewood and 1 water for me and you can have the rest. 

mturk_agent_2: Ok that sounds good

mturk_agent_1: Submit-Deal

mturk_agent_2: Accept-Deal
