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.

When I'm at home, I always need to pack extra drinks and snacks for myself in case I go into shock and need to take medication.

Being on a first time adventure, I lack these items as I was inadequately prepared.'
