The police department at the county where I work used to send cadets to Communications so they could get a feel for what dispatchers go through. I had my first clue of getting older when they looked more like high school students that 21+ year old cops.
Years later, when I was taking classes at Maryland, my increased temporal status was confirmed. I decided to throw my old bike in the back of the truck and use that to get from the parking lot to class and back. I was peddling up a hill in front of one of the buildings when my handlebars decided to get loose and go wonky. When I hit the brake, the handlebar took a hard left, the front wheel locked, and the bike tumbled over with me still attached. Laying in the road on my back, knee banged up and bleeding lightly, I see a lovely female student coming over and hear a soft, voice - "Are you OK, sir?"
