mturk_agent_2: Hello How you doing?

mturk_agent_1: Great! So since water is so heavy and the least desirable but needed, I will take most of the water and the wood. you can have the food and less of the other stuff. 

mturk_agent_2: Okay I'll take food need much more and you?

mturk_agent_1: I will take the water and the wood. I do think the wood is important too. Keep us warm, we can cook and boil water. SInce we are taking more food more firewood is a must too🙂

mturk_agent_2: Yeah Thank you very much both we take wood to share.
