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 will have my two packages of food and only one package of firewood. I do not think I can make one package of firewood last for both of my food. ' 'So is your counter that you get 2 packages of food, 0 of water, and 2 of firewood?' 'Yes, I would be happy with two food and two firewood. That would leave you with one food and one firewood as well as all of the water.'
Utterance: 'Ok that sounds fair I agree to that 🙂'
Example Output: No

Example Input: Context: 'Oh I see. You can have all 3 firewood if you are ok with me taking all 3 food.' 'Hmm, well I'd love to get some of the food. What I took 2 firewood, 1 food and 1 water? ' 'Sorry but I really need all 3 food. All the food I brought with me has spoiled because the AC in my car broke. ☹️'
Utterance: 'I see - So are you saying I would take all 3 firewood and all 3 water and you just get food? '
Example Output: No

Example Input: Context: 'hello' 'Hi how are you?' 'I am good. How are You.   I was just thinking about how I need extra water due to a medical condition.  How about I take all 3 waters?'
Utterance: 'I am okay. How about I give you one and half then I get some firewood from you?'
Example Output:
Yes
