I walked into a bookstore to kill some time before a meeting. I strolled to the psychology section with a vague idea of looking for a book about the development of the mind. As of late, I am tickled by evolutionary psychology. Instead, stymied by the size of the section, I picked up a book whose cover was facing me. It was by a “leading jury expert,” the cover blared. It promised “tips that reveal the truth behind body language.” In other words, it was about “reading people.” No sooner than I took the book from its perch and opened it at random, I came upon a revealing tip: “sarcasm is a sign of insecurity.” Beware of people who resort to sarcasm, that is. All I can say in my defense—for I have sinned, dear reader—is that I use sarcasm very sparingly. Besides, I promise to use it even more sparingly in the future, if at all. In fact, from now on sarcasm is plain out. Please, oh, please, give me another chance, dear reader! Or is it juror?
