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: 'food is necessary for all living beings. ' 'I am traveling with a big group so we need more water.' 'lots of water only for when u have thirsty'
Utterance: 'That's true but we don't want to be dehydrated either since we have so many people haha. Here's my suggestion: 2 waters for me and 2 food items for you?'

No
