Children's unexpected actions and thoughts make parenting both magical and exasperating. Some days you get serenaded with an off-key lullaby; some days you find pee in the sandbox and a naked culprit. I didn't see this picture happen. It was taken by a camera on a stand triggered to fire every three seconds. My older son crawled under the table after dinner, for reasons he later didn't remember, and his younger brother peeked at him. It was a small moment, one of many known and understood only by them.
