There are few things more humbling than falling down. Figuratively? Sure. A failure of any kind, a falling down of sorts, is tough. As much as people love stories of redemption, they are more sympathetic to the rising action than the falling action. But I'm talking about literally falling down. I'm specifically talking about a grown man, 42 years old, going rear over teakettle while doing something he's done a thousand times: running down a sidewalk. I expect this sort of thing from time to time from my young children.
