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.

I wanted to make a nice meal for my friends so I was hoping to be able to get extra food. 🙂' 'Oh well that's no problem. I'm packing a lot for our group. I'd be willing to give you all the food if you give me all the firewood?'

We'll need the heat source, but also for cooking.  It a big deal that I get the extra wood, I hope you will understand why I need it.'
Utterance: 'my people feel like they need 1 extra of something or else they will throw a fit ☹️'


Output: Yes
