Throughout our daily live we do things trying to become the gray man without thinking about it. If you've ever tried to avoid eye contact with an annoying acquaintance or a street vendor, you have tried to become the gray man.

You can talk about operational security and situational awareness without talking about being the gray man, but you can't talk about being the gray man without talking about operational security and situational awareness. Becoming unremarkable and unmemorable require you to understand your situation and act accordingly.

As I was growing up I was the gray man without even thinking about it. I was the quiet child that would always fly under the radar. My siblings were always busy talking, while I was always busy thinking about how to handle each situation.
