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: 'HI, I will have all of the packages of food and 2 waters and 2 firewood and you can have the rest. Unless none is needed for you then I will take them all.' 'i will need 3 firewood packets.  I have a terrible disease that prevents my circulation from working properly.' 'That does sound bad. I am going camping and my kids might want to stay up late so I will need extra firewood for this to keep light and more warmth. I will take all 3 extra of the food and the water but I need 2 firewood also.'
Utterance: 'no that won't work.  I will give you 3 food and 1 water.  I will take 3 wood and 2 waters.'
answer:
Yes


question:
Context: 'I have 10 people in my group' 'I see. I need more water because I came across some people who were lost and they are very dehydrated.' 'I need 2 firewood because it gets below freezing at night'
Utterance: 'Oh I wouldn't want for you to freeze☹️ It also gets cold where I am, so I need 2 firewood as well.'
answer:
No


question:
Context: 'Hey, nice interacting with you. I'll need additional package of water as I need to cook as well.' 'ok, if i get all 3 extra firewood, I'd be fine with getting 1 extra water while you get 2? food is a really low priority for me' 'Same here as well as I have carried enough but yes, I need firewood as most of y food requires cooking and specially my kids prefer having food hot.'
Utterance: 'Ok thats fair, I would prefer to have more firewood since I'm awful at collecting firewood while out. But we could be a more even split of it all. 2/1 for both. Do you need more water or more firewood?'
answer:

Yes
