“Twins woman is either one extreme of herself or the other. On first introduction, she makes a clear-cut impression—but fittingly that's only half the story. When next one meets her, she may have made a complete switcheroo—being not just slightly altered, but completely opposite in demeanor. Gemini pours on her separate personalities as something of a defense mechanism. She can sit at a dinner party and, quite literally, turn a separate face to the guests seated to her right from that to those at her left. She's tough as leather or frilly as lace, depending on the way she perceives those around her and how they may be of use. If playing the guileless, giggly waif works to her best advantage, so be it—but if being the wickedest witch in the Western world is called for, she can pull that attitude out of her pointed hat faster than you can say "my little pretty.”
