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: 'Great! For our camping trip, I would love to take all the water and firewood. You can have all the food. ' 'I really need the firewood,  It gets very very cold at night where I go camping.' 'I really needed firewood also.  I have brought my whole family camping which includes my 2 and 3 year old.  They really need to stay warm'
Utterance: 'I am just going to walk away,  I can't have my family freeze'
Example Output: Yes

Example Input: Context: 'Yeah, I think I'm okay with firewood, but I'd really like more food and water.' 'That fine then. If you want you can have most of the water and I can have most of the firewood. Sounds good?' 'That seems fine. How do you want to split the food? I grew up poor so I'm always afraid of starving 😮'
Utterance: 'Oh, yea I get that. I have a family so I need some food too. But just to clarify, are the original plan was to get 3 firewood for me and 3 waters for u right? '
Example Output: Yes

Example Input: Context: 'I can give you all the firewood - but as a diabetic, I still need at least one extra package of food for my blood sugar levels. So, as my final offer I can give you all of the firewood, and two extra packages of food. Do you agree to these terms?' 'No, I give out only one extra package of food' 'I think you misunderstood what I said. I said that *you* would receive all of the firewood, and two extra packages of food. '
Utterance: 'ok'
Example Output:
No
