Female Detectors

My excitement of the day was going to the federal building across the street where you have to walk through a metal detector to get inside and put your bags on a scanner, like an airport. I kept setting the stupid detector off and the guard had to wand me. The funny thing was when I was leaving the building this other girl was saying that she had no belt, nothing metal, etc.--in other words no reason for the detector to go off. Yet she too got wanded. Coincidence? I think not.
