Definition: 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.
Input: Context: 'If you want one water you can only have 2 foods. Do you really need the water? It sounds like food is a much more important item to you🙂' 'Ok I will take 3 food and 3 firewood and you can all 3 water? 🙂' 'No. I will need 1 firewood to agree to this deal. Otherwise it seems a bit unfair to me.'
Utterance: 'Ok I can work with that. I am so excited for my camping trip I can't seem to type a clear sentence lol 🙂'

No
