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: 'I want 3 packages of firewood, 2 packages of water, and a package of food' 'Not happening' 'If you do not come with a deal I would walk away'
Utterance: 'Bye then'
No
The utterance "Bye then" is the last utterance in the conversation and does not contain the self-need strategy. The self-need strategy 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. In this case, neither utterances were used to make a personal need statement or claim on any of items being negotiated (food, water, firewood). Therefore, No is correct..
