” To say somebody is a PP is to make a perfectly respectable medical diagnosis, like saying he or she has appendicitis or athlete’s foot. The classic medical text on PPs is The Mask of Sanity by Dr. Hervey Cleckley. Read it! PPs are presentable, they know full well the suffering their actions may cause others, but they do not care. They cannot care because they are nuts. They have a screw loose! “
- Kurt Vonnegut
