I have a hairdryer that switches itself on when I'm asleep alone in the room. Now that's scary. And one of my flatmates has a TV that frequently turns itself on at random times. At first we tried to blame it on electrical stuff (I'm a linguist and dressmaker, he's a lawyer, what do we know???), but then the shower kept turning on at all hours of the night. Yikes! fortunately the contract expires on thursday and we're moving out!
