Quote #7
I saw plainly that he was surprised, but he never attempted to draw my secret from me; and although I loved him with a mixture of affection and reverence that knew no bounds, yet I could never persuade myself to confide in him that event which was so often present to my recollection, but which I feared the detail to another would only impress more deeply.
