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 think that can be negoiated then i tend to eat less on camping trips' 'Great!  So looks like all the water goes to you.  I will take all the food if that is ok and we can split the wood.  ' 'Well i would need one food and one wood'
Utterance: 'OK.  I think that will work out for me.  You get 3 water, 1 wood and 1 food.  I will take the rest.'

No
