My packages kept vanishing after a young woman moved in across the street. One night, I caught her on camera stealing a box at 1 a.m.

Instead of calling the cops, I decided to teach her a lesson. The next night, I left a fake package outside—with something inside that would make sure she’d never forget what she did.

I filled the box with a bunch of small, noisy alarms and one of those glitter bombs people use for prank videos. When the package was moved, the alarms went off, and glitter exploded everywhere. I watched from my upstairs window as the young woman, wearing a faded green hoodie, grabbed the box. The second she stepped off my porch, a loud screeching noise erupted, and rainbow glitter covered her from head to toe.
