I've "misplaced" my watch once and it drove me insane. It eventually turned up, but the endless searching drove me crazy.
This thought occurred while my husband and I were talking about going through airport security and how comfortable I'd be taking off my watch. My cousin's Rolex never met her on the other side of the scanner. I was explaining to my husband that it was the perfect set up--passengers are in a rush with flights to catch, security lines are crowded and the TSA agent can just deny seeing anything. That's what happened in her case.
