Lenore Skenazy & Jonathan Haidt:

One day last year, a citizen on a prairie path in the Chicago suburb of Elmhurst came upon a teen boy chopping wood. Not a body. Just some already-fallen branches. Nonetheless, the onlooker called the cops.

Officers interrogated the boy, who said he was trying to build a fort for himself and his friends. A local news site reports the police then “took the tools for safekeeping to be returned to the boy’s parents.”

Elsewhere in America, preschoolers at the Learning Collaborative in Charlotte, North Carolina, were thrilled to receive a set of gently used playground equipment. But the kids soon found out they would not be allowed to use it, because it was resting on grass, not wood chips. “It’s a safety issue,” explained a day care spokeswoman. Playing on grass is against local regulations.

And then there was the query that ran in Parents magazine a few years back: “Your child’s old enough to stay home briefly, and often does. But is it okay to leave her and her playmate home while you dash to the dry cleaner?” Absolutely not, the magazine averred: “Take the kids with you, or save your errand for another time.” After all, “you want to make sure that no one’s feelings get too hurt if there’s a squabble.”
