Medium: Food
High: Water
value2reason: Low: It's pretty warm, and the daylight lasts a long time in the summer. It would be nice to have firewood, but not urgent.
Medium: My husband didn't pack any snacks for us at all, and our kids get cranky if they don't eat something small every now and then. We'd really appreciate having some food!
High: On my last camping trip I suffered from dehydration and passed out. I really don't want to repeat that experience!

Negotiation dialogue:
mturk_agent_2: Can you spare some water? I need to take medication and I have run out.

mturk_agent_1: Hi there, that sounds important. Yes, we can make sure you get some water. How does 1 package sound?

mturk_agent_2: I'd rather have 2, can give you all of my food for all of your water?

mturk_agent_1: I actually got really dehydrated on my last camping trip, so don't want to be completely without water. How about 2 for you, 1 for me?

mturk_agent_2: That is good, is it possible that I could get some firewood as well? I may be suffering from hypothermia.

mturk_agent_1: Oh wow! I don't want you to be that cold! :o  If I can have 3 food, I'd be happy for you to have 2 firewood.

mturk_agent_2: That would be great, I'm not real hungry, so I can spare some food.

mturk_agent_1: That sounds fair to me! So we've got 2 water and 2 firewood for you, 3 food and 1 each water and firewood for me.

mturk_agent_2: Yes, you're very kind. I desperately need some more water and firewood.

mturk_agent_1: I'm glad we were able to work out something for both of us! I hope you have a great camping trip!
