Q: 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: 'I want to go on hiking too. Since I don't go alone I need food and water.' 'I would be willing to sacrifice the majority of food in exchange for water and firewood.' 'This offer is good for me but I need some water too. Can we share the water and have all the firewood? 🙂'
Utterance: 'No, I offer you 3 food, and 1 water.  I would like 2 water and 3 firewood.'
A:
No
