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: 'No, I don't have any plans for this weekend. Can we camp together?' 'If you want to tag along, sure.  lol  I'll be heading to the mountains so it's going to be hot during the day and cold during the night.' 'Great, hey, I'll make you an offer, I'll keep 3 firewood, 3 food and...'
Utterance: 'Would I be able to take 2 firewood and 3 waters and then you take the res?'
answer:
No


question:
Context: 'I have a medical condition that causes my veins to close up when I get too cold. I will thus need the 3 firewood.' '☹️Oh, that sounds awful. Are you sure you need all three packages of firewood?'
Utterance: 'I might be able to get by with just two... I'm on a diet though, so I don't need as much food.'
answer:
No


question:
Context: 'Yes, I expect that! You need food most and I need water, so let's propose an exact trade? 3 for 3?' 'My main objective for the camp is food and firewood, since I have a large family and the amount of food they give in the camp is very small for all my family and my wife and I have to cook with firewood in the camp.' 'I understand completely. I would like to have all three water, and I'm only traveling with just me, so how about 1 firewood? The rest for you.'
Utterance: 'No me gusta mucho el trato, pero para eso debemos hablar y decidir como adultos un buen trato para los dos. Lo que queremos es disfrutar en el campamento.'
answer:

Yes
