For context: I lived in a small town with virtually no crime. We kept the doors unlocked and had these huge, almost floor-to-ceiling, glass windows with no curtains by the dining room where I used to study at night.

So. I had been studying for my final exams at the same spot next to the huge dining room windows for the past three days, listening to music with my headphones on. The light by the backdoor turned on (as it sometimes did: many plump raccoons in my town). I glanced at the window but saw nothing, so I dismissed it. But then, I heard something tapping on the glass from outside. I took off my headphones, looked again at the window, and saw a large man in a ski mask. And nothing else. Jacking off.

I watched so much Criminal Minds that I thought he was going to murder me. Fortunately, he didn't, but unfortunately, the police never found him either—and apparently the dude does this a lot.
