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.

Example input: 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.'
Example output: No
Example explanation: In this utterance, the participant does not use self-need since they do not talk about any need for themselves.
Q: Context: 'Hi there, that sounds important. Yes, we can make sure you get some water. How does 1 package sound?' 'I'd rather have 2, can give you all of my food for all of your water?' 'I actually got really dehydrated on my last camping trip, so don't want to be completely without water. How about 2 for you, 1 for me?'
Utterance: 'That is good, is it possible that I could get some firewood as well? I may be suffering from hypothermia.'
A:
Yes
