Given the task definition and input, reply with output. 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 self-need strategy, otherwise output No. self-need is a selfish negotiation strategy. It is used to create a personal need for an item in the negotiation, such as by pointing out that the participant sweats a lot to show preference towards water packages.

Context: 'Yeah, I'm going to the desert so I'm hoping to have enough water. I'm good on food and I hunt for a lot of it anyways.' 'I've never been a good hunter. I wish I had those abilities.' 'I would part with all the food if I could get all the firewood.'
Utterance: 'That seems fair. How about water. How would that be split? I'm very concerned.'

Yes
