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.

In addition, my family is from the South and will need firewood as well.'
Utterance: 'I can't swim too. I think two waters will help me to survive on this trip and I will need at least two firewood to make fish or other food items for my family. '
