Cave Dwelling

I get teased by my family about wanting to live in a cave. I don't like light, and I have never understood why, not that it matters a whole lot. But just to give an example, right now at three in the morning I am sitting in my family room with a TV on behind me, and the only other light in the room is the glow of four computer screens. There are lights in the room, I just choose not to turn them on most of the time.

It may have something to do with my depression. A dark room mimics how I feel inside most of the time, I think. And, I have to admit that right now I am pretty well depressed. But oh well, that's what therapy is for, right?
