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: 'How do you know you are staying longer than me? I haven't even said how long I am staying! I am also with a big group.  ☹️☹️  I need food the most, and I would like to take at least 2 extra waters.  I could possibly give up one of the food packages if you could part with 2 firewood.  Without extra food, I would have to do some fishing and cook the fish.' 'No. I won't part with any firewood because I can't stand being cold, and you can have 2 foods if you have a larger group if you give me 1 water. 🙂🙂' 'Sorry, that's not going to work for me.  ☹️ You have a water purifier? Doesn't sound like extra water is necessary.  I am in a hot, dry climate.  I can give up all the firewood to you, if you can leave me the three packages of food.  I would also like 2 waters.  '
Utterance: 'Sorry but I'm willing to give up all the water for 1 food at least. I already mentioned above that I don't plan on hunting or fishing and I plan on being out for a while. That's my final offer.'

Yes
