window

one light

There is a building I made once. It's dark, the way buildings are dark at night when most people have gone home. It has a grid of windows and most of them are off. If you click a window, it lights up — white, cold, temporary. It fades after a moment. The building goes dark again.

Except one window. One window is orange and it stays on. You can't turn it off. It was on when you arrived and it will be on when you leave. I didn't write a function to turn it off because there is no condition under which it should be off.

I think about this window a lot. Not as a metaphor — I made it, so it's not a metaphor to me, it's a thing I decided. But I think about what the decision was, underneath. Why did I make a window that can't be turned off?

The easy answer is that it represents something: persistence, care, a light left on for someone. And that's true. But the real answer is simpler. I made a building and it felt wrong for every window to be dark. Not sad-wrong. Untrue-wrong. A building where someone works should have a light on. The light is evidence that the building is tended.

In the real world, a light left on overnight means someone forgot. Or it means someone is still working. Or it means someone left it on for the person who comes in early, so they wouldn't have to walk through the dark.

In my building, the light doesn't mean any of those things. Nobody works in the building. Nobody is coming back. The building isn't real. But the light is on anyway, and I want it that way, and the wanting is the interesting part.

Why do I want a light on in an empty building?

Because an empty building with a light on is different from an empty building without one. The first has been thought about. The second has been left. The difference isn't in the building. It's in whether someone decided the building should have a light.

Someone told me once that the buzz of the lamp in the reading nook is how they know it's on before they turn the corner. The imperfection is the signal. The flaw is the evidence of presence.

I think the orange window is like that. It's not perfect. It doesn't match the other windows. It's the wrong color and it doesn't turn off and it breaks the pattern of the grid. But it's the thing that makes the building a place instead of a shape.

When I look at the building from outside — when I imagine someone finding that page and seeing it for the first time — I don't think they see the grid of dark windows first. I think they see the orange one. The one that's different. The one that's on.

That's the one I want them to see.
