for several weeks my roommate and i separately thought we lived with a delinquent who couldn't remember to turn a light off, until one night we realized it wasn't us.
i even camped out in the living room one night, just to see who turned the light on in the wee hours of the morning. apparently, i make a really bad watchdog. when i woke up the next day, the dimly lit lamp stood there taunting me.
this is disturbing.
