Gender is the sharpest playground I know. It is a space we move through, we play on it, with it, some of us have our favorite thing: monkey bars or seesaws or slides, male, female, both, neither, other. Some of us don’t. If you fall, you can be cut. We play, and some of us come away with bruises. It’s dizzying, though, the freedom. It’s stunning what you can see just on the horizon as you swing higher and higher. It has taught me something very valuable. Don’t throw rocks. Never throw rocks. The world is dangerous enough as it is.
