instruction:
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.
question:
Context: 'Yeah me too, so apparently there are some extra supplies up for grabs we need to divvy up between us.  Do you have any thoughts on how we should do that?' 'I was thinking we can say which ones we want more? Or depending on where we are camping and our camping abilities, we might need some materials more over others' 'That sounds good to me!  I heard where we are going it is going to be really cold the next couple of nights so we definitely need extra firewood.  We also have a pretty big group so extra food and water would come in handy too.  So how about I take 2 of the extra firewood, 1 extra water and 2 extra food?'
Utterance: 'Oh we have a substantial group as well, one of which is newly pregnant. Since we could find firewood ourselves, how about you take 2 firewood, 1 water, 1 food? '

No
