Selected quotation
"If you describe things as better than they are, you are considered to be a romantic; if you describe things as worse than they are, you will be called a realist; and if you describe things exactly as they are, you will be thought of as a satirist."
~ Quentin Crisp, "The Naked Civil Servant"
