Yesterday I went to the beach to fly the trainer kite. Not much wind, but it was fun. As I was walking home, I passed a character you'll see at pretty much every beach in the world: Mr. Sketchy. To my left a group of teen girls were splashing around in the water having a good time, probably oblivious to the fact that they are being watched intensely by a sketchy, middle-aged man in sunglasses. He sits there smiling like Kevin from The Office, staring at the girls.
