I went to work for a few hours on July 4. After awhile, I went outside to smoke, leaving my keys in the front door lock. I'm sitting on a step, 10 feet away is the front door, 10 feet past the door is my parked and locked car. It's broad daylight, and very quiet outside.
After a bit, I hear the kerthunk of the car unlocking itself. The keys hadn't moved, there was no breeze.
The night crew believe a former staffer haunts our building. Maybe so, but sorry dude, you can't have my car!
