An autist's introduction to Circling

The reason this essay exists is that I have heard dozens of people over the years say something like “Yeah, so I keep asking people to explain what Circling is, and everybody keeps refusing and claiming it’s impossible and that you have to experience it to understand and honestly it’s soured me on the whole thing.”

(Literally dozens. Refusing-to-explain-Circling is a thing.)

So I’m just going to jump right in with the explanation, as if you already wanted to know, and I’ll back up to stuff like Why and How afterward.
