I'm passing through the world invisibly. Even when people see or speak to me it's as if I didn't exist, as if I had no right to exist. I tread across their lands and they don't see me. I act and act and act and nothing makes any difference in the world. But they touch me.

The nature of parents is to embarrass merely by existing, just as it is the nature of children of a certain age to cringe with embarrassment, shame, and mortification should their parents so much as speak to them on the street.
