Given the task definition and input, reply with output. 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: 'I would like the 3 food packages because my sister forgot to pack any food items for the trip. You can have all the water and firewood. ' 'Oh no!  I have my daughter with me and she really likes to eat.  I was hoping to get at least some of the food.  Do you need water or firewood more?' 'I'm sure we can come to some compromise. I know my sister and I want to make s'mores in the evening. How about I get 2 food and 1 firewood, 1 water and you get the rest? '
Utterance: 'I love s'mores.  Food is my number one concern though.  If I'm only getting 1 of the food I really need all of the water.  How does that sound?'

No
