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: 'Yes I can give you the three food but I need 2 water. I can become very thirsty. ' 'Yes that is totally fine with me. What about firewood' 'I can give you 1 of the firewood. I would like to stay warm at night so I want 2. 😮'
Utterance: 'Hmm that's going to be hard for me because I also get cold. what other reasons do you have?'
Yes
