Medium: Firewood
High: Food
value2reason: Low: I don't go through much water, so I think the normal amount would suffice for me. 
Medium: I am very small and get very cold at night. I need the extra wood for warmth.

mturk_agent_1: Hello

mturk_agent_2: Hello, how are you? 

mturk_agent_1: Good, any particular item you're looking for?

mturk_agent_2: My highest need is more food.  I am a diabetic and need to keep my blood sugar up. 

mturk_agent_1: Gotcha, we can work on that. Any interest in firewood as well?

mturk_agent_2: Well I have interest in all of the items but food is most important.  I would like some more wood as I am small and tend to get cold at night.  What is your highest need item?

mturk_agent_1: My biggest need is water, it's going to be incredibly hot hot where I'm going so I'm looking for as much as possible. Also, hence the need for not a whole lot of firewood.

mturk_agent_2: I have the least need for water so I'd be happy to give you the water and I'll take the wood if that's of no use to you.

mturk_agent_1: That's perfect, I'd like 1 of the food if possible. However seems like you need the extra bag more than I do.

mturk_agent_2: That sounds like a good deal to me!

mturk_agent_1: Great so 3 waters to me, 3 firewood to you and 1 food for me, 2 for you?
