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.

Utterance: 'I would like 2 wood, 1 water and 1 food. You would get 1 wood, 2 water and 2 food.'
Output:
