Hazards of working on the 13th floor

I'm not superstitious, I promise.

I work on the 13th floor, and there's something hinky with the elevator. Car #3.

At least half the time I walk near the elevator shaft, Car #3 is either open, or opening.

Walk out of the bathroom? Ding! and the doors are opening. Like it hears you coming. (I'm not superstitious, but not opposed to anthropomorphicization...)

Here's the best part. When you get on the elevator, the 7th floor lights up. On its own. As the doors close.

So, Unlucky 13, Lucky 7, and then the lobby.
