It happened with spring, too: I didn't realize it had sprung until I looked at the Google homepage. The seasons just sneak up on me.
People who know me know I am not a fan of fall. It's the ever-darkening lead up to winter, of which I am even less a fan. And in some sense, it's worse than winter: in winter, at least the days are slowly lengthening again, a long wait before the rebirth you know is coming. Fall is death itself.
