At Paul's one-year checkup, the nurse was going through her checklist of developmental milestones. Does he play interactive games? Does he have separation anxiety? Does he wave bye-bye? ...Bye-bye? That one took me a second. Paul doesn't wave bye-bye, because he's never had to. My biggest regret with Joseph is dumping him in daycare at three months. But Paul? He's always had the good life, and he has a smile to match.
