Most left-handers I know write with their hands curled around the pen, which slants to the right, thus achieving the approved slant. I'm amazed at their determination, as it looks very tiring and quite unnatural. My mother, who was also left-handed, wrote a straight-up-and-down script with her left hand, and a fine Ontario School Hand -- but backwards and upside-down -- with her right. That was a really neat-o parlour trick.
