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.

Input: Consider Input: Context: 'I agree! We can figure out working out a deal! What if I gave you 2 food and 2 waters and you gave me your wood and one of food/water? If that doesn't work for you we can also figure something else out.' 'I think that sounds reasonable. Of course, I could counter with I take 2 food, 2 waters and 1 firewood. What do you think of that?' 'That is also good. This is hard to work out since it's uneven haha. What about if I give you all my food, you give me all your firewood, and then I can give you 2 waters?
