Bob Greene: My father was incredibly industrious, mechanically brilliant in terms of his ability to sort of make sense of things. The contrast was, for a variety of reasons, that I understand better now than I certainly did as a kid. And my two siblings, all of us had some form of ADHD or ADD. So when you're a little kid in that kind of environment, you're learning really fast how to protect yourself initially. and then how do I potentially protect other people? Early on, the strategy was be quiet. When I learned how to talk more and engage more, questions were an overcompensating strategy to avoid getting in trouble.
