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.

Example Input: Context: 'Well I am happy to give you all my food in exchange for all your water.' 'We can do that! How do you want to split up the firewood?' 'It's an odd number so someone has to get 2. But in order to make it fair if one of us takes two then the other should get one of the lower priority items. What do you think?'
Utterance: 'That sounds fair to me! I am good either way.'
Example Output: No

Utterance: 'Hmm, I need food too. I am willing to split. I will give you 2 food since you claimed it first. Can I have 2 waters then?'
