Has anyone ever told you, "You're so vain!" If yes, we hope you didn't feel bad. "You so vain" is not really a bad statement. You should probably feel flattered as it probably means that you look good and healthy. Vanity is something one shouldn't be upset about, and whoever said a vanity is a crime probably needs a good facial and haircut.
