On a lighter note, my 2nd year resident had a funny story - he had been treating a woman for crack dependence, and she had admitted to not only smoking crack and drinking throughout the pregnancy, but also continuing to smoke crack, and leaving her baby alone so she could smoke crack. Needless to say he reported her to child services after her less than enthusiastic response to him suggesting she should stop.
...Cut to the cafeteria a few weeks later. He's in the cafeteria, when deranged crack mom bursts towards him screaming and swearing, "I'm going to kill you! You're a rotten doctor! I can't believe you reported me to CSB!" etc. etc. People are scattering out of her way...meanwhile the resident is just standing there looking slightly puzzled. She stomps right up to him continuing to swear at him and yelling, "I could just spit in your face!" as she continues her little deranged tirade. Meanwhile the resident is still standing there with this vaguely puzzled look on his face. "Weren't you scared?" we all ask him. "No," he replies, "Because I was still trying to figure where the hell I knew her from...after a while all the crazy people tend to blend together..."
