Negotiation dialogue:
mturk_agent_1: Hello there.  I am excited about this camping trip!

mturk_agent_2: I'm also excited, I love the outdoors!

mturk_agent_1: My favorite thing to do is sing songs and tell stories around a campfire.  Consequently, I was really hoping to get some additional packages of firewood. 🙂

mturk_agent_2: I do love sing alongs around the campfire. I usually go hiking and it requires a lot of energy and fuel. Maybe I can get additional food packages?

mturk_agent_1: You'll definitely need some additional calories if you want to do extra hiking.  I will give you all the additional food if you give me all the additional firewood. 

mturk_agent_2: Sounds like a deal, maybe split the water packages evenly. Can't be dehyradated while camping 🙂

mturk_agent_1: Agreed.  Your fun trip could turn into something quite dangerous without that hydration.  

mturk_agent_2: Of course, that won't be fun. ☹️ So we have agreed

mturk_agent_1: Mostly - since we cannot split the water 1-1, do you mind if I take the extra one? 🙂 

mturk_agent_2: That's fine, you might need it more.
