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: 'You came here to work? I’ve been taking it easy. ' 'LOL, I mean setting up the tent and clearing the area for a campfire. I'll take a break now.' 'Sounds good.  I suggest you make a fire and relax. '
Utterance: 'Just need a little more wood.  Then it will be great to cook my dinner on.'
Output:
Yes
