instruction:
The input is taken from a negotiation between two participants who take the role of campsite neighbors and negotiate for Food, Water, and Firewood packages, based on their individual preferences and requirements. Given an utterance and recent dialogue context containing past 3 utterances (wherever available), output Yes if the utterance contains the vouch-fair strategy, otherwise output No. vouch-fair is a selfish negotiation strategy. It is used to call out fairness for personal benefit, either when acknowledging a fair deal or when the opponent offers a deal that benefits them. This can be through an explicit call out or can be implied.
question:
Context: 'Hey, I am excited to go camping too!  Would you mind sharing your top priority items with me so that we can come up with a fair deal?  Ideally I would love 3 firewoods, 3 foods, and 2 waters just like you aha.  But perhaps we can each get at least 3 packages of our highest priority item ' 'Hmmm, I think I really need the firewood.  I brought softwoods and they burn out quickly so I don't think I'll have enough wood to keep me going through the night. I get kinda scared without the fire.  What is your priority?' 'Okay, well firewood is also my top priority since it will be so cold tonight.  But I would be willing to take only 1 firewood (and give you 2) as long as I got 2 foods and 2 waters '
Utterance: 'Thank you for the offer on firewood.  I think that sounds fair.  However, I really would like at least 2 waters as well. '
answer:
Yes


question:
Context: 'That might work. What reasons do you have for needing those?' 'I want to make smores and a nice dinner' 'I feel like I might need more firewood, I'm staying in the desert and it gets cold at night.'
Utterance: 'I could do one firewood and all the food?'
answer:
No


question:
Context: 'are you hiking alone?' 'no i will have my husband and my dog with me' 'oh nice well how about you give me 3 water and I give you 3 food and we figure out the wood make a suggestion'
