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: 'I was hoping to get some extra food for some picky eaters, but if they are hungry they will eat!' 'Oh no! I know how picky eaters can be. I'm sorry to hear that. So are you thinking I'll give you the one food, and 2 firewoods, and 2 waters? Will that work for you?' 'Yes, that works.'
Utterance: 'Deal!'

No
