mturk_agent_2: Hello there.

mturk_agent_1: hi

mturk_agent_2: So I plan to go hiking a lot this trip and I would appreciate a majority of the water and firewood if possible.

mturk_agent_1: I want to go on hiking too. Since I don't go alone I need food and water.

mturk_agent_2: I would be willing to sacrifice the majority of food in exchange for water and firewood.

mturk_agent_1: This offer is good for me but I need some water too. Can we share the water and have all the firewood? 🙂

mturk_agent_2: No, I offer you 3 food, and 1 water.  I would like 2 water and 3 firewood.

mturk_agent_1: Well this is perfect for me. I agree with 3 food and 1 water. Do you also agree?🙂

mturk_agent_2: Sure that sounds fair to me, we both get what we need.🙂

mturk_agent_1: Then is a deal! Hope you have a good trip!
