wow you think the weirdest things. my dad was a lefty. he was also trained to be a righty cuz the catholic church was very against left handers. because of this his handwriting always suffered. as to left versus right brain, i forget which does what. i know my dad was way more into English, and had a weird logic all his own. both things i inherited from him, plus my terrible handwriting. but i don't ever recall being left-handed, so its quite possible his being left handed had nothing to do with it.
