Detailed Instructions: 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.
Q: Context: 'I agree that we will! I do love having food as well. Have lots of people coming.' 'I'm not as keen on food, so how does this sound.  I get 2 firewood, 2 waters, and 1 food.  You will get 2 food, 1 firewood, and 1 water. ' 'Hmm, you're getting my top item there though. That still might work.'
Utterance: 'I think it's pretty fair since we'll both get at least one of our top item (firewood) and you get more food (I assume your second priority) and I get more water (my second priority)'
A:
Yes
