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: 'Ah, so you want some extra water too? I have a lot of lemonade mix for the kids so I'll need water for them.' 'I tend to get dehydrated quickly so if I don't have enough to drink I won't be able to provide everyone with food.' 'Well, we have extra food too. How about I take 2 water, 1 food, and give the res (1 water, 2 food, 3 firewood) to you?'
Utterance: 'That's super thoughtful of you. However, I really need two waters so I can provide for everyone. Once we have enough food and fire we can always go get water from the stream and boil it for the kids.'

Yes
