I took pleasure, not only in the pleasure of the deed, but in the praise. What is worthy of dispraise but vice? But I made myself worse than I was, that I might not be dispraised; and when in any thing I had not sinned as the abandoned ones, I would say that I had done what I had not done, that I might not seem contemptible in proportion as I was innocent; or of less account, the more chaste.--From The Confessions of Saint Augustine--
Even saints lie about it! This is the kind of stuff they need to teach in sex-ed classes.
This has me thinking though: people often do bad things because they worry about what other people might think of them.
