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: 'I'm great! Just getting excited to go camping and dreaming of all the food I'll eat! Do you have any extra food?' 'Let me ask you, do you need food most? If yes, what do you need second most?' 'I would love as much food as is available. I would also appreciate excess firewood, as I get cold.'
Utterance: 'Okay, it seems we both have the same priorities in food most and firewood second most. How about this, you take 2 packages of food, I will take 1. You give me 2 packages of firewood I will give you 1. We will then divide the water. Is that fair?'

Yes
