I'm a lefty, though the nuns tried their best to convert me. When repeatedly removing the pencil from my left hand and putting it in my right didn't work, they left me to figure it out on my own. To this day I still hold a pen in a "unique" fashion.
There are only two things I cannot do left handed: use scissors and shoot a pistol (though I shoot a rifle left handed - how's that for bizarre?).
all us lefties are confused with our handedness i'm afraid.
