"Is anyone really normal?" -- Asperger's Syndrome is the psychiatric diagnosis du jour for thousands of adults who were previously thought of as "rude, clueless or just plain weird" by their friends, family and coworkers. It's a form of mild autism that prevents the person from understanding social cues like body language, small talk, inside jokes, etc. There's tons of information online, from the basic to the quirkily personal. There's even an Asperger's romantic comedy being filmed with Josh Hartnett...hmmmm. And for a little comic relief, try the Institute for the Study of the Neurologically Typical.
