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 small-talk strategy, otherwise output No. small-talk is a cooperative negotiation strategy. It is used for discussing topics apart from the negotiation, in an attempt to build a rapport with the opponent. For example, discussing how the opponent is doing during the pandemic or sharing excitement for the camping trip.

And you have 1 food, 1 water and 2 firewood, right?' 'that sounds good to me, if you want to give me another food i would take it but ok if not '

Example Input: Context: 'Haha yup I had a feeling about that one. ;-) Yeah my wife has a bunch of crazy hikes planned so water is a must here too. What else?'

Okay so let's try this... one of us gets 2 waters with 1 firewood and 1 food. I think that's as close as we'll get to equal. You can choose.'
