Admit it: Once you've decided to end it, the painful part isn't ejecting Mr. or Ms. Wrong from your life; it's facing the music when you break the news. There are, quite understandably, personal safety issues to consider. Well, buck up, all you heartbreakers out there: At the airport, all the security work has been done for you. Step One: Feign a trip for you and the one you don't love. Step Two: Pass through the metal detectors, where the threat of sharp objects will be removed. Step Three: Tarry beside the M16-wielding National Guarders who inevitably hang around the luggage checkers, then proclaim the split. If the announcement goes over like a Bowie knife in a suitcase, call in the camo.
