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: 'What do you need the extra water for?' 'With the extra food I need I will need extra water also.  How about I only take 1 extra water?  ' 'So are you okay with you getting 2 food, 1 water, and 1 firewood and me getting 1 food, 2 water and 2 firewood? I'll do that deal.'
Utterance: 'That should work.  I will conserve with my water and I should be fine.  So we have a deal?  '
Example Output: Yes

Example Input: Context: 
Utterance: 'Hi . How is your camping trip going?'
Example Output: Yes

Example Input: Context: 'Let's talk about what we need. First, I don't eat meat, so I really feel like I'd need a little extra food, as I couldn't hunt or forage for food at all. I feel like I could survive without a ton of water, but would need water, as I hike a lot and cant trust any sources' 'I've also planned my trip to include a lot of hiking and so I have a high priority for extra water, as like you've said you need to stay hydrated on your hike and you can't trust any source. How can we divide up the water as that seems to be the number one priority for us both.' 'That works well, as long as I can have 2 food, I'll certainly give you 2 water, and I will have one water and you'll have one extra food'
Utterance: 'I would be most happy to make a concession on the food for an extra ration of water. Are you going to require any firewood if you don't need any I think i'll take the 3 rations so I can have a nice bonfire.'
Example Output:
No
