Perhaps it comes sooner for most—the parent’s warning not to cross the boundaries of a particular neighborhood, or the frustration of not having hair like Barbie no matter how long you tease and comb, or the tale of a father’s or grandfather’s humiliation at the hands of an employer or a cop, overheard while you’re supposed to be asleep. Maybe it’s easier for a child to receive the bad news in small doses, allowing for a system of defenses to build up—although I suspect I was one of the luckier ones, having been given a stretch of childhood free from self-doubt.
