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 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: 'HI, I will have all of the packages of food and 2 waters and 2 firewood and you can have the rest. Unless none is needed for you then I will take them all.'
Utterance: 'i will need 3 firewood packets.  I have a terrible disease that prevents my circulation from working properly.'
