Woke up this morning to a dark house. It was an early rising, and I’m used to coming downstairs to  dim light and shadows, thanks to a fluorescent light over the kitchen sink that has become so much a fixture that I don’t notice it anymore — unless it’s out, as it was today.

Gone were the shadowy shapes of the worn couch and wing chairs. Gone the hutch and table. Gone the carpet and trim. Instead, the blue dial of the clock radio face asserted itself, and the microwave timer threw its glowing dots into the void.

It was a different downstairs that greeted me this morning, a blank and mysterious one. One that made me realize that what I usually think of as darkness isn’t that at all. It’s only a dusky substitute.
