Often when I am walking or running in the pre-dawn hours, a street lamp will suddenly go dark. The first time it happened, I wondered if perhaps a man with a long, silvery beard, wearing buckled boots and a purple cloak would emerge from the shadows. Could Albus Dumbledore be in my neighborhood? I know, of course, the impossible nature of what I wonder. Professor Dumbledore is a beloved character first introduced in Harry Potter and the Sorcerer's Stone by J.K. Rowling. A magical device could not snuff out the street lights with a click and a pop. Still. It somehow comforts me to imagine him watching me, giving me a "lights out" signal.
