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: 'Hello, I would really like to get most of the water and firewood packages.' 'You can have most of the water and firewood if I can have most of the food. I would like to get two of the firewood so I have a nice fire to come back to after searching for a source of water.' 'How about I take all off the water, 1 firewood and 1 food package? 🙂'
Utterance: 'You can have all of the water if I can have all of the food. I promise that I will bring you back food. I am really good at foraging and I know all about what is edible in a forest 🙂 I want to have two packages of firewood so that I can have a roaring and hot fire going when I come back from being out all day. I am sure that I will find some fish to catch at my water source! 🙂 I'll bring some to back to share with you!'
Example Output: No

Example Input: Context: 'That is simply unacceptable.' 'well how about i get 2 water, 2 food and 1 firewood' 'Here is the offer.  For you: 3 water 0 food 1 firewood'
Utterance: 'what about instead of firewood, I get 1 food, so it will be 3 water, 1 food and 0 firewood'
Example Output: No

Example Input: Context: 'I have enough food too. Can I take 2 water, 1 firewood and 2 food?' 'How about two water, 1 firewood and 1 food, since we both value water the most?' 'Is that what you want or what you are offering?'
Utterance: 'That's what I'm offering to you, but I think it's a fair deal, so I'd accept it myself, too.'
Example Output:
No
