instruction:
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.
question:
Context: 'Hi there.  I'm hoping we can make a deal about me getting firewood.  I get really cold at night and I'd love to have my fire still going in the morning for coffee - I'd gladly share some if you pop by my campsite.' 'I am in dire need of firewood myself. I was planning on bringing food that needed to be cooked over flame. 😮' 'Well maybe we can find a way to split it!  This isn't a problem we can't solve.  Are you in need of food too, then?'
Utterance: 'That would be great! I don't need food as much as I am in need of firewood, to be honest.'
