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 will definitely need 2 packages of food and 2 of firewood for survival.' 'I am definitely ok with giving you two of the firewood!!  Why do you need 2 packages of food?' 'I have a very fast metabolism and a dog to take care of. Thanks for the firewood.'
Utterance: 'Awe!  We have a dog as well, I love dogs!!  How about if you get 1 package of food, 1 water and 2 firewood?  Would that be sufficient for you?'
Example Output: Yes

Example Input: Context: 'Same here! I am in need of food more than firewood however as I am very hungry. ' 'Me too. We have a bigger family and we will run out of food if we don't get some more.' 'Since it looks like we have the same value ranking for our needs, how would you like to try to make the deal?'
Utterance: 'Well let's try to make this as fair as possible.🙂We could get 2 packages of food, leaving you with 2 extra packages of firewood as well as water.'
Example Output: No

Example Input: Context: 'I would need firewood to cook my food as well. I would like the 3 water, 1 food, and 1 firewood, what about that? ' 'Since the value of water exceeds both food & firewood, I think it's fair for me to receive the extra dose of firewood. My offer to you is: you get 3 water, 1 food,  0 firewood.  I would get 0 water, 2 food, 3 firewood.' 'Okay you have a deal.'
Utterance: 'Great. I'll send it over '
Example Output:
No
