You will be given a definition of a task first, then some input of the task.
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: 'That is fair. Could I also have 1 food so I do not starve' 'what about your basic food rations?' 'I am severely malnourished and could use just one more food please'
Utterance: 'we got kids on this trip, they need food too.  also, your basic supplies should keep you fed well enough to not starve/be malnourished'
Output:
No
