For example, discussing how the opponent is doing during the pandemic or sharing excitement for the camping trip.

Example Input: Context: 'I know this isn't your problem, but I'm a student and I had to come up here to take photos of the night sky for my astronomy class. I slept really late today as I have to sit up all night to get the different stars, and possibly even the space station if it's clear enough out. I have to sit by a fire to stay warm so I can get these pictures to hand in to my professor tomorrow.' 'You know that is very impressive.  I admire your determination and effort you put into your class.  You must be very passionate about astronomy.' 'I am. My favorite personality is Neil DeGrasse Tyson. He's amazing, funny and incredibly smart. I'm hoping to get an internship at the Planetarium in my senior year 🙂'
Utterance: 'That's amazing!!!  So here is the deal...I'll give you the 2 firewood packages so you can sleep under the stars tonight.  In return I'll have to keep 2 water packages and 2 food packages since I won't be able to cook all of this fish and I still have a family to feed.  '
Example Output:
Yes
