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 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.
Input: Context: 'Hello, fellow camper.  Are you ready for our camping trip?' 'I am ready to go camping. I understand there might be some disagreement around the additional supplies we each can choose from?' 'There could be.  However, I think that if we are both reasonable, we should be able to come to an agreement.'
Utterance: 'I think so too. I have a medical condition - type 1 diabetes - that makes it important to bring extra water and food. I'd like to request more of those two items.'
Output:
Yes
