When I was younger I found a stash of porn in my parents room so I decided to watch it when they were gone for the day. While having the VHS tapes strewn about the floor, I heard the front gate open, so I ejected the tape and grabbed the rest, shoving them under the bed. I couldn't exit through their room because it lead directly to our front door and I could already hear their keys jangling, so I had to close and lock their door, essentially trapping myself inside.
When the front door opened up, the only thing I could do was exit through their balcony, so in desperation I climbed the side of the railing and jump down about 10 feet, calmed myself down, and chilled out in the basement hoping no one would notice while I watched something on tv.
Next thing I know, it's my brother coming down the stairs looking around cautiously, asking me if I've been upstairs. Of course, not wanting to get caught, I said no, but then this sudden look of shock washes over his face. He proceeds to explain how he heard these loud noises coming from the house and noticed the lights were on. He was thinking it was me, but my parents bedroom door was locked and no one had the key but them (I was able to slide a firm sheet of plastic down the side).
To this day, he tells the story of when he came home and heard a poltergeist that left the lights on and how he scared the hell out of him.
