Quote from : Atonement Book

But this first clumsy attempt showed her that the imagination itself was a source of secrets: once she had begun a story, no one could be told. Pretending in words was too tentative, too vulnerable, too embarrassing to let anyone know. Even writing out the s, the s, made her wince, and she felt foolish, appearing to know about the emotions of an imaginary being. Self-exposure was inevitable the moment she described a character's weakness; the reader was bound to speculate that she was describing herself. What other authority could she have?
