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: 'Hello partner  How are you today?' 'Oh, I'm a bit ill, fever, chills.' 'SO do I😮!!!  That is not good.'
Utterance: 'No it's not.  Since my fever is very high and my chills are very bad I'd appreciate you letting me have 2 firewoods and in exchange you could have all the extra food.'
Output:
Yes
