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.

Ex Input:
Context: 'Well I am happy to give you all my food in exchange for all your water.' 'We can do that! How do you want to split up the firewood?' 'It's an odd number so someone has to get 2. But in order to make it fair if one of us takes two then the other should get one of the lower priority items. What do you think?'
Utterance: 'That sounds fair to me! I am good either way.'

Ex Output:
Yes
