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 too need extra water, but I'm willing to negotiate on the other things if you are! 🙂' 'If I take 2 waters, will you accept 2 firewood?' 'You take 2 waters, I'll take 2 firewood and 2 food?'
Utterance: 'What about you take 1 water and the firewood.  I take 2 waters and all the food'
Example Output: No

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: 'Sounds good. I'll be doing quite of a bit of cooking over an open fire during my trip.' 'Wow. That sounds great! There's nothing like campfire cooking on a chilly night! I'll doing a lot of that too, but I also want to enjoy swimming as much as I can🙂 ' 'understood, I can give you 1 firewood, 2 food, and 2 water to make your trip better.'
Utterance: 'Hm. I''ll definitely take you up on the water, thanks for that. The thing is, I have low blood pressure, and I have trouble regulating my body temperature so I am frequently cold. How about if I take two firewood, and the two waters. It sounds like you are going to do a lot of cooking, so you can take two of the food.  '
Example Output:
No
