It is easy to slip into a parallel universe. There are so many of them: worlds of the insane, the criminal, the crippled, the dying, perhaps of the dead as well. These worlds exist alongside this world and resemble it, but are not in it.

This time I read the title of the painting: Girl Interrupted at Her Music. Interrupted at her music: as my life had been, interrupted in the music of being seventeen, as her life had been, snatched and fixed on canvas: one moment made to stand still and to stand for all the other moments, whatever they would be or might have been. What life can recover from that?

Are you crazy? It's a common phrase, I know. But it means something particular to me: the tunnels, the security screens, the plastic forks, the shimmering, ever-shifting borderline that like all boundaries beckons and asks to be crossed. I do not want to cross it again.

Confuse was the nurses' word for abuse.

And this was the main precondition, that anything might be something else. Once I'd accepted that, it followed that I might be mad, or that someone might think me mad. How could I say for certain that I wasn't, if I couldn't say for certain that a curtain wasn't a mountain range?

Crazy isn't being broken or swallowing a dark secret. It's you or me amplified. If you ever told a lie and enjoyed it. If you ever wished you could be a child forever.

It's important to cultivate detachment. One way to do this is to practice imagining yourself dead, or in the process of dying. If there's a window, you must imagine your body falling out the window. If there's a knife, you must imagine the knife piercing your skin. If there's a train coming, you must imagine your torso flattened under its wheels. These exercises are necessary to achieving the proper distance.
