Why We Helicopter Parent: If you've never thought much about what happens when your child's bus gets to school, and who meets it, and how supervised kids are as they make their way into school, a terrible story about a girl with autism and what happened when she got off the bus should prompt you to ask those questions. And feel better about watching your child walk all the way into the school building, if you do the drop-offs yourself. And justify any vigilance you may show in, say, monitoring e-mail or Facebook activity. The world's just scary.
