Negotiation dialogue:
mturk_agent_2: Hi. What items are most important to you?

mturk_agent_1: Hello. My friend Dale just called and said Him and Jimmy are coming up for the night. I was expecting them at all. They are brining plenty of water but we are short on food.

mturk_agent_2: I see. That is great that your friends can come. I would love to help.🙂

mturk_agent_1: That's awesome maybe we could trade 3 waters for 3 food.🙂

mturk_agent_2: Actually,  I did not bring enough warm clothes and blankets and we need the extra firewood to keep us warm.

mturk_agent_1: I can spare some fire wood not a lot but some.

mturk_agent_2: oh no, but I really need all that I can get. I am willing to give all the water you need in exchange

mturk_agent_1: I do not need water at all we have plenty.

mturk_agent_2: I see. I don't need any water either as I have a stream at my camp

mturk_agent_1: O ok
