 In the Coddling the American Mind, Greg and I talked about how kids used to have free play. You and I, I think we're about the same age. I was born in 1963. We grew up during a big crime wave. There was some danger out there. But all kids went out to play. It would have been totally unnatural for parents to say, no, you stay inside. Eight-year-old, you're not allowed outside. We all went out to play. And that's how you learn basic social skills. That's how you get tougher. That's how you learn to manage risk.
