pSam paged me at 9 p.m., crying. It had started with his hair, which he was convinced was falling out. And although his work as a teacherrsquo;s aide had ldquo;filled him with love and joy,rdquo; he was sure his boss had given him a nasty look at the lunch break, and he felt utterly sick inside. Later Sam had phoned his partner, who had seemed distant. Afraid he was about to be dumped, Sam locked himself in the staff bathroom and cried for almost an hour, failing to finish his work and preventing others from using the facilities./ppSam is a drama queen--a person who reacts to everyday events with excessive emoton and behaves in theatrical, attention-grabbing ways. This type is the friend who derails a casual lunch to tell you a two-hour story about the devastating fight she had with her partner or the co-worker who constantly obsesses about how he is about to lose his job and needs your support to make it through the day. The drama queen worships you one minute and despises you the next, based on overreactions to minor events./p a href=http://www.scientificamerican.com/article.cfm?id=dangerous-liaisons[More]/a
