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.

Example Input: Context: 'I agree, can't wait to unplug. As far as supplies go, I think its going to be hot and sunny where I'm going, wouldn't mind a bunch of extra water.' 'Water is extremely important to me too.  I can give you 2 waters if you give me all 3 firewoods. ' 'Hmm, ok, thats pretty fair. I do have a larger group going as well, so would it be okay if I got 2 extra food then?'
Utterance: 'I think that will work. '
Example Output: No
