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: 'Hi there, how are you doing?' 'I am great. Excited to go camping. How much food do you need?' 'I could use some extra food, I'll be hosting a get-together at my campsite later and will need some to entertain the guests. I'd like 2.'
Utterance: 'That is fine. I can go fishing to get some extra food but I would still like one. Can I take two packages of firewood so I can cook them? '
answer:
Yes


question:
Context: 'I am allergic to tea and coffee. I wonder if the smaller fire would be more quaint for everyone to sit around. ' 'It really wouldn't do the job that well at all.  You could always prepare hot cocoa or use your share of the food to make a warm stew.  I really do need at least the two firewood and a couple of food.  You can have all the water to make a hearty and hot stew to get your through the night, though.' 'I can't eat much anyway because of the health issues. You could have all of the food if I could get the extra firewood. That would still give you an extra firewood in addition to the basic supply and lots of extra food for your party. I'm sure they would love having some of the stew you mentioned.'
Utterance: 'Well, how about I take just the one extra firewood, plus all of the food, and one of the water so that I can make stew?  Would that work for you?'
answer:
No


question:
Context: 'I'm doing well. I'm looking forward to going on my camping trip but will need some additional items to make sure the trip is safe, healthy, and enjoyable. ' 'Same here. ' 'I have diabetes, so it is very important to me that I get extra packages of water and food. When I'm at home, I always need to pack extra drinks and snacks for myself in case I go into shock and need to take medication. The trip could be very dangerous for me if I don't have access to these additional supplies. '
Utterance: 'Actually mine own purposeful need is firewood and water. Being on a first time adventure, I lack these items as I was inadequately prepared.'
answer:

Yes
