Do you not feel this way about it yourself? I know I would.
Many many many years ago, I was a wee IT manager. Sort of a weird company, I was too young to be much more than smart kid who can install / fix anything.
Anyways, worked a few years there, made some friends, had one CAD engineer who was an utter jerk. In hindsight, probably a bully, but at the time just a really irritating person.
So that was my first foray into small electronics… worked up a small breadboard with a 555, some source of randomness I don’t remember now, a piezo speaker, and a 9v battery. It would emit a short beep at random intervals between roughly 60 and 240 minutes.
Stashed it above the ceiling tiles in his office on my last day at the company.
Good times. I bet it’s still magnetically attached to the inside of the steel riser column of one of their desk chairs, though the battery is likely long dead.
So I may in the future be the villain in a story like this if I am forgetful when I sell my apartment.
My upstairs neighbor is a moron who has flooded their apartment at least twice, so I have stashed moisture sensors into the access panels in multiple rooms as a sort of early warning system.
