Example Input: Context: 'Pretty good. Just hanging out with our group. Looking forward to this upcoming camping trip. It's a college reunion weekend. ' 'Oh.  That sounds fun.  I'm getting ready to go camping with my family next weekend as well.  It will be the first time that my kids have gone camping with me.' 'Aw that will be a great time then 🙂 How old are your kids? '
Utterance: 'My kids are 14 and 12.  So they're fairly independent - but I also know that they want to do a lot of cooking during our camping trip.  Thus, I think that I'm going to need more firewood as I expect that we'll be having a lot of fires while we're out.  How about you?  What are you planning to do on your camping trip?'
Example Output: Yes

Example Input: Context: 'Hello, I'm hopping I could grab most of the food, I have a lot of hungry mouths to feed.' 'Hi - I can understand that. I have quite a few mouths to feed as well'
Utterance: 'hmmm, well what are you looking to get'
Example Output: Yes

Example Input: Context: 'Pretty good!  I am looking forward to going on this camping trip with my family.' 'Same here! We had a couple bumps in the road though, as our freezer stopped working so all our food went bad ☹️' 'That is rough ☹️  We should try to split the resources equitably then'
Utterance: 'Ya definitely. I need food and firewood most. What do you need?'
Example Output:
Yes
