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: 'Lol, at least it sounds like you've got an expert with you. My husband is really gung-ho but he tends to fly by the edge of his seat when it comes to stuff like planning. He's says he wants to travel light and that he got these water filter straws so that we could drink lake water but I'm super sketched out... I don't want us getting something like schistosomiasis. And I want to make sure everyone stays hydrated with all of the hiking they want to do' 'I get that. I'm going to risk it with the lake water because I'd personally love to have enough food to last 3 weeks (which I'm a little worried about as it is), so I can definitely help you out with the water.' 'thanks! where do you plan on camping? I know popular places are worried about spreading Covid and a lot of offices that give out camping permits are closed.'
Utterance: 'We're going to check out Acadia National Park. I'm not totally sure on the details, I'm letting my boyfriend plan and I'm just handling the packing haha'
Example Output: Yes

Example Input: Context: 'I need a lot of food, because of how many people are coming now (like 3 times as many). Also, there's only one stream in the area and it's really far from our campsite, so it would be super inconvenient to have to hike there everyday to refill our canteens. We are in a forest though, so we should be good for wood. Since you can easily fish, what if I take 3 food and 2 water? You can keep all the firewood. 🙂' 'Well I have to have some food and I don't need all of that water.  How about I take 2 water, 1 firewood, and 1 food.  I do need the firewood to cook the fish but I dont need it to keep warm at night because I have hefty sleeping bags that work excellent in the cold.' 'That could work, but I'm still a little worried I won't have enough food for 6 people. How long are you guys going to be camping for?'
Utterance: 'I will be camping for 3 day so I gotta have some food.  Although, I do understand your situation.'
Example Output: Yes

Example Input: Context: 'I can understand that. I know I really need the food the most. I'm already worried I'm going to run out. I also have blood sugar problems, so I cannot run out ☹️' 'Thats fine. If you want you can have 2 foods and I get 2 of the fire wood. Sounds fair?' 'And I would take 3 water? '
Utterance: 'That would be a problem since I need the water too. I was hoping that since you got 2 foods ill get the 2 waters'
Example Output:
No
