It was like being in an elevator cut loose at the top. Falling, falling, and not knowing when you will hit.

Once I was in Texas, where they had this thing called Ralph the Swimming Pig. You went into a theater and you were looking through a great big window at people dressed as mermaids swimming around with oxygen tanks. One of the mermaids had a bottle of milk, and a small Ralph the Swimming Pig dove in and swam over. Naturally, afterward, I said in the cafeteria, "What happens to the Ralphs when they get bigger? Would you serve Ralphs who have retired?" "Oh no! We would never do such a thing."

When we cracked the genetic DNA code, opened the big Pandora's box, and it really did become possible to produce chimeras, my ears shot up. Having been brought up among the biologists and having followed various debates about ways to improve the human template and other debates about the true nature of our nature, I began seriously to wonder: What if?

I walk away from him. It's enormously pleasing to me, this walking away. It's like being able to make people appear and vanish, at will.

A wave of blood goes up to my head, my stomach shrinks together, as if something dangerous has just missed hitting me. It's as if I've been caught stealing, or telling a lie; or as if I've heard other people talking about me, saying bad things about me, behind my back. There's the same flush of shame, of guilt and terror, and of cold disgust with myself. But I don't know where these feelings have come from, what I've done.

Ah men, why do you want all this attention? I can write poems for myself, make love to a doorknob if absolutely necessary. What do you have to offer me I can't find otherwise except humiliation? Which I no longer need.

But who can remember pain, once it’s over? All that remains of it is a shadow, not in the mind even, in the flesh. Pain marks you, but too deep to see. Out of sight, out of mind.
