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: 'You can have all the water if we can have all the food?' 'I dont think I am okay with that ☹️. Food is essential to our groups morale when camping. We would like 1 additional food preferably.' 'Well you guys did say you did not care much about large fires. What if you gave all the firewood in replace for the water and you can still keep 1 food?'
Utterance: 'So I would get 3 water and 1 food and youd get 3 firewood and 2 food?'

No
