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: 'Got it! I am going to need the most of food. There aren't any animals or berries that I feel safe eating where I'm going.' 'Well I think we can make a good deal then.  How many packages of food would you want?' 'Could we each do 3 of what we need the most? I get three food and you get three water? How do you propose splitting up the firewood?'
Utterance: 'We can do the 3 for 3 trade.  That works perfectly!  Its' going to be cold at night where I'm going.  What's it like where you're heading?'

Yes
