Woke up this morning to discover that a light bulb had mysteriously jiggled itself out of alignment in a wall-mounted lamp. Shrinking/swelling of the heated bulb, no doubt. OK, jiggle the bulb back, lights work, all is well.
As I'm about to leave the apartment, I turn on the outside light (as I still get back after dark), and it blows with a POP! I can hear while still inside my front door. Did I piss off some illumination demon? Weird.
