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: 'Hello there.  I am excited about this camping trip!' 'I'm also excited, I love the outdoors!' 'My favorite thing to do is sing songs and tell stories around a campfire.  Consequently, I was really hoping to get some additional packages of firewood. 🙂'
Utterance: 'I do love sing alongs around the campfire. I usually go hiking and it requires a lot of energy and fuel. Maybe I can get additional food packages?'

Yes
