Shortly after learning I have Aspergers, I realized my social skills needed work, so I began reading this and similar books. It's easy to read, but I found myself taking ample time with each page due to how substantial every section is. Even the passages on hands, which I never thought of as too socially important, proved to me how essential handshakes and explanatory gestures can be in interpersonal communication. This is a must have for anyone interested in social psychology, and an excellent source of info for anyone with social awkwardness.
