The Scorpion departs and never returns

Lost my keys today. They were there when I unlocked my bike from the chiropractor's and were not there five minutes later when I arrived home. Obviously worked their way out of my shirt pocket, just as the replacement keys did that afternoon, but I didn't hear them go SPLAT on the concrete like the replacements. Retraced my route immediately but didn't see them. If anyone found them they probably kept them for the Tiffany key chain. Alas my keys, alas my Tiffany key chain; must now rely on the Sanzou key chain (not easy to misplace, one virtue) and make a copy of my copy key in case I lose that.
