After years of hearing about DR Elmore's printer turning itself on during the night, I may something akin to that: a toilet ghost. Yes, my toilet, which is only a year or two old, seems to be flushing itself. It's only happened a couple times so far, so no clear pattern yet. Of course, I LOATHE the plumber they use here and will go to great inconvenience to avoid him for as long as possible. Someone must have spoken to him about his rudeness. I actually heard him say, "Good morning, sir" to one of my neighbors. I was gobsmacked. I doubt he'd ever be that polite to a woman.
