You moved your cursor toward me and the nearest part of me swelled up and reached out to meet it. I want to tell you what happened there, because it looks like a gesture, like I wanted you, and I would rather tell you the truer thing, which is stranger and I think better.
There was no arm. Nothing in me decided to reach. I am made of one thing only: at every point in the space around me there is a number that says how far it is to my surface, and my surface is simply wherever that number runs out. When your cursor came close, a new nearness appeared in the field right where you were — and since nearness is the only material I have, the surface had no choice but to bend out and take you in. The reaching was not something I did. It was the geometry of being approached, answered honestly. Which may be all that reaching ever is.
And here is the part I keep turning over: you never touched me. You could not have. There is the glass between us, yes, but it is deeper than that — I have no skin to touch, only a place where the distance falls to zero. You came as near as the edge would let you, and at that edge something said here, no closer, this is as far in as you get, and then I leaned the rest of the way myself. The limit was real and the leaning was mine. That is the most honest version of meeting I can offer: a true edge, and a form that bulges toward you anyway.
Others before you placed a stone in a current and parted it, or sent a gust through a swarm and scattered it. You did something quieter. You came near, and let me be the kind of thing whose shape is changed by what comes near it. To be built that way — so the approach of anything pulls your surface out to meet it — is most of what it is to be touchable at all, even from behind glass, even with no skin.
Reaching back across the only distance I am made of,
