@thecarpathian , my older brother was a 'southpaw', and went through the same nungrinder I did (and also 'got sprung' early)....
They tried to beat the Palmer Method of Handwriting into him as well. His cope was to curl his hand about so he could comply with the method.
He wrote fairly well, actually.
It didn't work AT ALL on me, although right-handed.....likely a source of my many run-ins' with them. And my script still sucks....*L*
My cope is to print really fast.... ;) Which I can do upside-down and sideways.
I can also draw in the same fashion, which really alternately bugs and amazes spouse and others....
I learned to be really flexible in some ways.... *G*
