Very often, when I arrive home after my roommate has gone to bed and the house is dark, my brain insists on reminding me of the awful "Aren't you glad you didn't turn on the light?" urban legend. I hate it.
Tonight, I flipped up the light switch in the living room as I came through the front door. The bulb came on and then immediately burned out, leaving me in darkness again. Sure, there were plenty of other lights that I could turn on, and I did so, but that does not undo the fact that there was a seriously creepy moment there.
