I walked into a glass door last Tuesday. It wasn’t one of those graceful, cinematic stumbles where you catch yourself and laugh it off with a stranger. It was a full-speed, forehead-first collision with a sheet of floor-to-ceiling tempered glass that I was absolutely certain was an open hallway.
The impact didn’t just rattle my teeth; it fundamentally insulted my sense of spatial awareness. For three seconds, I stood there staring at my own faint reflection, wondering how my brain had managed to delete a physical barrier so completely from its rendering of the world.
The mistake wasn’t that I was distracted. The mistake was that I had walked through that specific lobby six times that week, and the door had always been propped open. My brain had built a rule: this space is empty.
When the janitorial staff finally closed the door for the sake of the air conditioning, my rule didn’t update. I applied a perfectly accurate memory to a situation that had changed, and the result was a bruised nose and a very public loss of dignity.
