Medium: Firewood
High: Food
value2reason: Low: Staying hydrated is incredibly important especially when active. Camping may entail physical activities that will dehydrate us. And so, it is important for us to be prepared with water. 
Medium: Having extra firewood is a smart choice to make, considering implications of weather. At night, the cold may hinder our ability to stay warm and healthy. In addition, firewood can assist in not only our warmth, but the heat necessary to make food.
High: While there is enough food, having extra is always important due to outlying conditions that make occur unexpectantly. When camping, it is important to be prepared at all costs.

Negotiation dialogue:
mturk_agent_1: Hello! 

mturk_agent_2: Hello there! How are you?

mturk_agent_1: I'm doing well! Just want to have some open communication on the packages for our camping trip! I'm very excited for it!

mturk_agent_2: I'm also looking forward to it. I'm planning on going back-country camping with a lot of hiking, so my top two priorities are firewood and water.

mturk_agent_1: Understood! My top two priorities are food and water! Am hoping we can reach a compromise on the items so that we're both happy!

mturk_agent_2: That sounds great, I'm the most flexible on food. How many of the extra packages of food do you want?

mturk_agent_1: I am hoping to receive 2 packages of food so that way you also have 1. 

mturk_agent_2: That sounds great to me. I'm hoping to get 2 firewood, 1 water, and 1 food out of the deal. I'm amicable to more discussion though.

mturk_agent_1: This also sounds like a fair deal to me! I am happy that we have reached a compromise so quickly on the packages based on our needs! 

mturk_agent_2: Me as well! I'm glad we could come to such a comprimise.
