The Diary of Anne Frank

Dearest Kitty,
A very strange thing has happened to me. (Actually, 'happened' isn't quite the right word.)

Before I came here, whenever anyone at home or at school talked about sex, they were either secretive or disgusting. Any words having to do with sex were spoken in a low whisper, and those who weren't in the know were often laughed at. That struck me as odd, and I often wondered why people were so mysterious or obnoxious when they talked about this subject. But because I couldn't change things, I said as little as possible or asked my girlfriends for information.
