I swear the women's bathroom at work has its very own Moaning Myrtle. Nearly every day there are unexplained trails of puddles and drips all over the floor (but not leading to or from devices that emit water), and the handicapped stall door has an alarming habit of swinging slowly open a minute or two after you've carefully set the latch. If I accidentally forget the door key in a stall, it sometimes falls on the floor while I'm washing my hands, reminding me to go get it. Today some very odd and unidentifiable scratching and splashing were coming out of the handicapped stall. Very mysterious!
