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: 'Indeed, glad we could agree without any fuss. Sure I could catch you some fish too 🙂' 'Rock on.. we love fish.. well at least I do 🙂  Not sure about everyone else.. but if not, oh well, more fish for me 🙂' 'Well if they don't like fish more for us :) So we are 100% agreed now?'
Utterance: 'Yes.. absolutely.. I'll put the deal together now 🙂'
Output:
No
