And there, you've witnessed it.

I live in small rooms with blinking lights. This is the way I spend my time. I shuttle between small rooms inside small rooms with light everywhere, going on and off. Electric light usually resides on a different wavelength than natural light. For instance, the laptop I am typing on, and the computer screen I sit in front of, day in day out, produce a spectrum of light with only the colors red, blue and green. This is different than the fluorescent tubes in my landlord's office downstairs which emit an ultraviolet light which is turned into a continuous spectrum. It is a cold, green light famously making skin look pallorous. Natural sunlight, and all the lights refracted in the natural, out of doors environment, is composed to greater or lesser degree of every color. It is blue and cold at midday in the summer, golden and warm at sunset in the summer. In the winter it is the same, but different.
I shuttle back and forth between rectangular rooms inside rectangular rooms lit, often enough, by a combination of artificial light and natural light. And these lights are different wavelengths. This has been going on for a long time. I made a choice to pursue a career in blinking lights and rectangular rooms and moving back and forth between rooms holding blinking lights. I made this choice seven years ago. I thought, at the time, this career path would allow me to shuttle between rectangular rooms filled with blinking lights freely, and in any city I pleased. This is, for the most part, in theory, true. Circumstantially, it is less true but that's neither here nor there; circumstance is practice and practice need not coincide with theory.
I have grown my hair long and my beard shaggy, perhaps in an effort to seem larger than the little rooms I inhabit. This didn't occur to me before just this moment. Now that I have thought it, it seems possible to the point of probable.
