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: 'It will be nice to get out and explore the great outdoors, even if it is super hot!' 'I agree. What supplies could you use more of?' 'Water for sure, need to stay extra hydrated.  How about you?'
Utterance: 'Haha yup I had a feeling about that one. ;-) Yeah my wife has a bunch of crazy hikes planned so water is a must here too. What else?'
answer:
Yes


question:
Context: 'Oh no! I hope you are okay! ' 'Yeah, I'm okay now.  It's just that I need to have a lot of food around to be able to manage it properly.  Like on this camping trip.' 'I totally understand! I am in need of food too, but it sounds like you really need it so I am hapy to give you all of the food if I can have all of the firewood?'
Utterance: 'What is your need for water?  I could use some of that, too.'
answer:
No


question:
Context: 'Yes I do! I was to ask you that in this conversation, will you be Okay with any agreement?' 'Let's see what we are both thinking and negotiate from there. What are your first thoughts on the additional camping packages?' 'I need all the food packing and some basic needs for the camping, may I know about your first though on which you need additional package?'
Utterance: 'I will need food packaging as well, so unfortunately I cannot agree on you taking it all. I will need 2 of the food packages, 1 of the firewood, and 2 of the water as I want to ensure to feed/hydrate my family of 5.. Does this work for you?'
answer:

Yes
