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: 
Utterance: 'Hello! I'm so excited for this camping trip. What do you still need as your supplies?'
Example Output: Yes

Example Input: Context: 
Utterance: 'Hello, great to see a fellow camper.  Planing on doing any hikes.  My family and mother-in-law are down getting some new trail maps.  We are looking forward to the long camping weekend.  Our bad luck was the airline loss two of our bags that had our food and water.  So i am hoping to get some more.🙂'
Example Output: Yes

Example Input: Context: 'No. Because I brought a water purifier but don't plan on hunting or fishing. So I'd be willing to give up all the water but I want 2 of the food.' 'I see.  I also greatly need the extra food, as I indicated. Perhaps there are some convenience or grocery stores near your campground--you might then purchase extra food there and not have to carry it with you on your trip?  ' 'I believe there won't be any convenience stores around to buy food, And I plan on staying out longer than you so I will need more food to last me, Do you need food or water more?'
Utterance: 'How do you know you are staying longer than me? I haven't even said how long I am staying! I am also with a big group.  ☹️☹️  I need food the most, and I would like to take at least 2 extra waters.  I could possibly give up one of the food packages if you could part with 2 firewood.  Without extra food, I would have to do some fishing and cook the fish.'
Example Output:
No
