My daughter graduated college, but got a job near there and still lives down there. My son is still in school, but still at home. They're both a joy to talk to - okay, most of the time. We go to a handful of hockey games every season, and my son is a veritable chatterbox at those. He's been like that since he was a little kid - at 4 and 5 he was making better observations about the games than most of the adults around us. My wife laughs because he'll text me constantly if I go to the game with his sister (it drives his sister nuts), and if he goes to a game without me, my phone buzzes constantly.
Yeah, it's rough because we remember so much of when they were little, but it's a journey for them, too.
