It is strange, the things that turn out to matter.

For years I had prided myself on a spotless home — had thought of the order as a kind of achievement, evidence of a life well managed.

I understand now what that order had cost, and who had paid for it, and I have come to love the mess with something close to reverence.

A mug left on the counter means a woman felt free to set it down and walk away without bracing for a consequence.

Toys across the rug mean a child played until she was called to dinner and did not once think to hide the evidence of her own childhood.

The finger-paintings on the refrigerator — crooked, gaudy, taped up at a five-year-old’s eye level — are the single most beautiful decoration my home has ever held, because each one represents an afternoon my daughter spent making something for the pure joy of it, in a kitchen where no one was going to tell her that joy had to be earned.
