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: 'HI, I will have all of the packages of food and 2 waters and 2 firewood and you can have the rest. Unless none is needed for you then I will take them all.' 'i will need 3 firewood packets.  I have a terrible disease that prevents my circulation from working properly.'
Utterance: 'That does sound bad. I am going camping and my kids might want to stay up late so I will need extra firewood for this to keep light and more warmth. I will take all 3 extra of the food and the water but I need 2 firewood also.'
Example Output: Yes
