I am convinced that human life is filled with many pure, happy, serene examples of insincerity, truly splendid of their kind-of people deceiving one another without (strangely enough) any wounds being inflicted, of people who seem unaware even that they are deceiving one another.
For someone like myself in whom the ability to trust others is so cracked and broken that I am wretchedly timid and am forever trying to read the expression on people's faces.
