Joyce Carol Oates said this quote

You people who have survived childhood don't remeber any longer what it was like. You think children are whole, uncomplicated creatures, and if you split them in two with a handy axe there would be all one substance inside, hard candy. But it isn't hard candy so much as a hopeless seething lava of all kinds of things, a turmoil, a mess. And once the child starts thinking about this mess he begins to disintegrate as a child and turns into something else--an adult, an animal.
