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.

Ex Input:
Context: 'I'm well! Excited for this camping trip.' 'Same! I'm a little worried about some of my supplies though. What about you?' 'Likewise! What are you most in need of?'
Utterance: 'Well, I'm camping up on a snowy mountain and I gave some of my food away to hikers who were passing me and were very tired and hungry, so I'd really like to get some more food. Firewood would be useful too, although I do have a thick coat and a sleeping bag. I plan on melting the snow to get water, so I don't think I'll need that too much. And you?'

Ex Output:
No


Ex Input:
Context: '☹️ I forgot most the food I was going to bring and only have enough for less than half the planned trip.' 'I understand. I guess we are in the same predicament. I have two kids with me though and they are hungry too. How long are you camping for? We are here a week.' 'I let my two girls bring their friend. Its their first overnight trip for more than a night. We also had a week planned.'
Utterance: 'My kids really eat a lot. But then yours probably to as well!'

Ex Output:
Yes


Ex Input:
Context: 'Since I arrived with no water at all, I would definitely need at least 2 waters.  I'm afraid I don't have a lot of "wiggle room" with that.  I'm open for the other supplies.  Ideally, I would like to have 2 waters, 1 firewood and 1 food portion.' 'If that's the case, I would like 1 water, 3 firewood and 3 food portions.' 'Would you be open to me having 2 waters, and 1 food portion?  While trying to get together some wood to start a fire, I came across a stray pup.  He seems very friendly - so I'm thinking he must have gotten separated from his family.  He's very hungry though - an extra food portion would be a great help.'
Utterance: 'Deal'

Ex Output:

No
