> But the kindest thing I can do, the thing that will actually make my daughters resilient, is to let the small problems happen.

I live in an average California suburb. Average priced homes, relatively quiet street, not really any disorder or even appearance of disorder. When I let my kids play in the front yard - minding themselves - neighbors call the cops. I've written about this before, and it's not simply a matter of choosing to let your own kids have more freedom.

There are simply no kids outside anymore so if yours are, they stand out. Kids playing outside is now so outside the norm and neighbors on edge that they will call the police. The police will not ignore it, and you or your kids will have to contend with a police encounter. This has the effect of making parents perform a calculus every time their kids ask to play outside.

If there's a way to get neighbors to feel that kids playing in yards is normal, I'm all ears.
