Detailed Instructions: 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.
Q: Context: 'I do need at least one extra water bottle in case the fire goes out of control, but I am willing to forgo any food as I can forage for food.' 'Alright. Thanks. I only ask for so much of the water because I am overweight and I know while camping I'll work up a huge sweat.' 'Great, that sounds good to me, are you okay with keeping all the food or would 3 be too much?'
Utterance: 'I'd be ok with keeping all the food. I do eat a bit too much and if for some reason I get lost it would be helpful to have!'
A:
Yes
