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.
One example: Context: 'That sounds pretty reasonable as I am in need of firewood the most. Would it be most reasonable to each take what we need most and split the water down the middle?' 'Yes, it would.' 'I think that sounds fair. The problem is that there are 3 waters and one of us would get two and the other one. How should we sort that?'
Utterance: 'You can take the two water. I am not that thirsty most days.'
Solution is here: No
Explanation: In this utterance, the participant does not use self-need since they do not talk about any need for themselves.

Now, solve this: Context: 'I would really like to have 3 waters and 3 firewood because this is my first time camping and I don't have survival skills. ' 'You must be a comedian.  We will need to come to a compromise because there's no way that's going to happen.  I am like a water buffalo so I'll need at least two waters.  In addition, my family is from the South and will need firewood as well.'
Utterance: 'I can't swim too. I think two waters will help me to survive on this trip and I will need at least two firewood to make fish or other food items for my family. '
Solution:
Yes
