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: 'I do need more food than firewood, If I could get 3 food and 2 firewood. You can get 3 water and 1 firewood.' 'I do need some food. I would like to get at least 1 food. You can still get 3 firewood.' 'I could use water as well, so I could get 1 water, 2 food and 2 firewood'
Utterance: 'I am good at making fire and have a starter so I can give up all the wood.'
answer:
No


question:
Context: 'I can't swim too. I think two waters will help me to survive on this trip and I will need at least two firewood to make fish or other food items for my family. ' 'You don't need this water to swim.  You can take two of the food if you're worried about food.  I will take two water and two firewood since I have a large family to nourish and keep warm.  Your initial suggestion of 3  waters and firewood is laughable.  Please provide a realistic compromise.' 'If I take two waters, 1 firewood, and 2 food supplies, this will help me during the trip. It seems as if you are more skilled than I am on a camping trip. Please consider my request☹️'
Utterance: 'LOL - not a chance.  You're going to have to give me more than that.  I am more skilled and thus need firewood.  How about this...I will take 3 firewood and 2 food.  You can take all the water because you're so non-skilled in the wilderness. I am going to hunt for my food, but again I have a large family.  I am not considering your request  at all.  We will need to come to a decision relatively soon.'
answer:
Yes


question:
Context: 'hello, how are the preparations coming along?'
Utterance: 'Hi There, I'm doing okay with my preparations but I am worried that I don't have enough food or water for the next few days.'
answer:

No
