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: 'Same here! We had a couple bumps in the road though, as our freezer stopped working so all our food went bad ☹️' 'That is rough ☹️  We should try to split the resources equitably then' 'Ya definitely. I need food and firewood most. What do you need?'
Utterance: 'I believe that we have the same priorities.  So we have a large family including children that need the food, but my wife also needs firewood due to poor circulation.  She is susceptible to frost bite and limb loss'
Yes
