One of the good things the Army took from us for deployment was cell phones. Not that they confiscated the cell phones, but we were not allowed to walk and talk on cell phones from the beginning of training in Oklahoma through out-processing at Fort Dix. The ban included the blue light blinking ear pieces that allow the user to talk on the phone without holding the phone.
For several years before deployment I would be surprised by seeing someone walking toward me talking in an animated way to no one. It usually turned out to be a guy arguing with someone wearing one of the blue light ear pieces. The blue light made the guy look like some kind of animated out-of-shape alien.
This morning in Philadelphia a guy was walking toward me on the subway platform talking to himself. I thought he was on the phone because some phones work in stations now. But as he passed by waving his arms I realized he was actually crazy and talking to himself. He wasn't on the phone. In the last couple of weeks I have been in Boston and NYC and also seen real crazies, not guys just looking like lunatics but talking on ear pieces.
It's always nice to see Old School hanging on.
