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.

Context: '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.' '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?' 'I need more firewood, I can maage with 1 additional package of water.'
