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 other-need strategy, otherwise output No. other-need is a selfish negotiation strategy. It is used when the participants discuss a need for someone else rather than themselves. For instance, describing the need for firewood to keep the kids warm.

Example Input: Context: 'I’m doing fine. How about you?' 'I'm doing well. I was hoping I could have the extra firewood because my group decided to camp for a few extra days and want to make sure we have enough' 'How many of you are on the camping grounds?'
Utterance: 'It's just my family. There are 6 of us total'
Example Output: Yes

I really enjoyed my time in Boy Scouts and look forward to practicing what I learned to good use'
