Dearest Kitty, It seems like years since Sunday morning. So much has happened it's as if the whole world had suddenly turned upside down. But as you can see, Kitty, I'm still alive, and that's the main thing, Father says. I'm alive all right, but don't ask where or how. You probably don't understand a word I'm saying today, so I'll begin by telling you what happened Sunday afternoon.

—The Diary of a Young Girl,
