I can take long walks, as I understand Greta Garbo does, and no one interferes with my thoughts and tranquility. Come to think of it, the other day I was on Fifth Avenue in New York and I saw a woman who could very well have been Garbo; I was a bit tempted to go up to her, but then I thought, "My God, practice what you preach! If it is her, you'll be intruding - just the thing you don't like yourself."
