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: 'I think that would work for us!' 'I am willing to make that deal.' 'Perfect! Let's plan on this between the two of us. Thank you for working so well with me. You made good points and I appreciate finding a proper solution. 🙂'
Utterance: 'Your welcome.  Have fun at the Puget Sound!🙂🙂'
Example Output: Yes

Example Input: Context: 'HI. I'd love to get 2 additional packs of firewood. The weather forecast was for much warmer weather here and I just didn't bring enough with me. I also left my additional sweatshirt at home. I'd be happy to give you one additional water and two of food.  🙂🙂' 'Well I had a really great day fishing today and I would like to have some extra firewood so I can cook all of this fish.  How about I take the 3 packages of firewood and you can keep 2 additional food packages in return.'
Utterance: 'You really did have a good day didn't you! Sounds like fun. How many fish can one person eat? If I don't have the extra firewood I'm going to be really cold tonight. ☹️'
Example Output: Yes

Example Input: Context: 'Same for me!!' 'What sort of extra supplies are you looking for?' 'I would really appreciate if I am able to take 2 of the food packages since I am a vegan and its hard to find options in the woods and if i can have 2 or 3 of the waters because i have a baby coming with me and i need it for his formula! '
Utterance: 'I think I can help with that, but in exchange, can I have 3 firewood bundles? I hate to take from the forest and risk damaging the natural wildlife habitat.'
Example Output:
No
