One thing I don't want to forget about this autumn, when Sam was about to turn 10: That it was his first summer to help mow the yard and when he'd walk behind that loud push mower he didn't realize that he wasn't in a sound proof bubble.
He'd circle the front yard behind that big, red beast, belting out songs at the top of his lungs. He could barely hear himself, so he figured there was no way we could hear him.
Sometimes he even threw in one handed dance moves, being careful not to let go of the mower's handle. It cracked me up, every single time.
