-- @home.com is bogus. Q: Dear Dr. Science,I've heard of vicious circles. Do the other geometric shapes have corresponding moods? - Leeann Cronbaugh A: They do, but most are much nicer than the mean-spirited circle. Ovals are graceful, spirals are sensuous and French curves are positively sexy. On the other hand, squares are boring and triangles are grating, while rectangles are second rate squares, and trapezoids are defective rectangles. As we progress along the axis of negativity, parallelograms are drunken rectangles, rhomboids are squares with a drinking problem that hasn't yet progressed to true alcoholism, and parabolas are ovals with a pathological fear of commitment that causes them to remain perpetually open-ended. So compared to the rest of this geometric menagerie of dysfunction, circles aren't much worse than the norm.Received on Thu Jul 19 2007 - 13:30:24 CDT
