Negotiation dialogue:
mturk_agent_1: Hi, how's it going?

mturk_agent_2: Good!

mturk_agent_1: It's brutally hot here. I'm so looking to go camping this weekend where there's a lot of tree cover lol.

mturk_agent_2: Oof, I get that. I'm trying to go camping too actually. I definitely need some extra water before I go, though.

mturk_agent_1: yeah I need water as well. but the kids are really looking forward to making s'mores and reading ghost stories by the campfire

mturk_agent_2: Is there anything you feel like you need? It sounds like you could use some extra firewood

mturk_agent_1: If you want 3 water then I can take 3 firewood. They kids are active so maybe I can take 2 food?

mturk_agent_2: Honestly that sounds like a fair deal to me 🙂 I'm camping just with my partner so we probably won't need quite as much food as you.

mturk_agent_1: Ok cool that sounds good to me. I'll send over a proposal for 3 firewood, 2 food and 0 water. That's ok?

mturk_agent_2: That means I'll get 3 water and 1 food, yes? I will agree to that.

mturk_agent_1: Submit-Deal
