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, it's hot here too! We are always in the 110-118 degrees out in the desert. What kind of dog do you have?' 'She is a Corgi with a fluffy coat so she is not a big fan of the heat. I guess you get a dry heat near the desert. We have a lot of humidity which is oppressive. Hoping it will be cooler on our camping trip!' 'Oh yeah, it's really dry here. I sort of prefer that. I haven't been in humidity much but it's so gross feeling. Corgis are adorable! Okay, I think we're ready to make a deal. It was so nice chatting with you!'
Utterance: 'Same here! Thanks for your cooperation. It was so nice to chat with you. Stay safe, well AND cool!'
Example Output: Yes

Example Input: Context: 'Aww I'm sorry to hear that, it sounds like it might be better to have her bring her own food. I'll be bringing my teenage son so it would be awesome to get any extra food for him that I can. You know how they be! 🙂' 'What about I take 2 of the packages and you take 1? I know teenagers also drink a lot of water haha 🙂' 'He definitely does drink a lot of water, but he's in a growth spurt so 2 would be ideal. I'm happy to give up all firewood in exchange for the extra food!'
Utterance: 'okay that sounds like a better deal then! I will take all the firewood and 1 food, and you can take the 2 food packages'
Example Output: No

Example Input: Context: 'Oh, that won't really work for me. I was hoping to get extra food and water for this trip since I need water to take medication and would love the food to plan a special meal. I'd like say, 2 food, 3 water and 1 firewood' 'I could give you 2 food, if I could have 3 firewood and 2 water' 'Hmm, how about I take 2 food and 2 water and you can have all the firewood?'
Utterance: 'This is fair, but I do not have any use for much firewood. I could give you 2 firewood, 2 water and 1 food'
Example Output:
No
