It's reaching my 2 year anniversary of moving into my building flat, nearing a chipper(noisy) 83 years old. I've noticed a strange occurrence that I'm unable to explain. Every two weeks or so, all the light bulbs in the flat become unscrewed. Now not simultaneously, but each bulb in a revolving two week sequence. This includes; closets, the antique fixtures built into the sides of the wall, bathroom, kitchen, art room, hallways etc. I've asked each of the tenants in the other 3 flats if this has happened to them. Cue up the X-Files theme, because instead of answers, they went hard at work on their theories. Nearly caused me to aggravate my hiatal hernia holding in the laughter. Look at these: "You know a police officer was killed in that exact flat......." "You know, I've always thought there was something strange going on...." and my favorite "Airport vibration" The Long Beach Airport is 6 miles north of here. They don't even fly in this direction. Okay, so I'm no Mike Hammer. I've reached a dead-end. Any possible logical explanation on how this could happen? Did the gentleman in #1, nail it with his response? "Yo man, you trippin'?"
