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.

Context: 'Sounds good. I'll be doing quite of a bit of cooking over an open fire during my trip.' 'Wow. That sounds great! There's nothing like campfire cooking on a chilly night! I'll doing a lot of that too, but I also want to enjoy swimming as much as I can🙂 ' 'understood, I can give you 1 firewood, 2 food, and 2 water to make your trip better.'
Utterance: 'Hm. I''ll definitely take you up on the water, thanks for that. The thing is, I have low blood pressure, and I have trouble regulating my body temperature so I am frequently cold.
