I think I mentioned it around here once, but YEAH, I held my pen/pencil wierd. I forget exactly how, but teachers commented on it, etc... I had a tutor because my classes sometimes had tasks where we had to write stories, etc... and frankly I didn't like anything I wrote. The tutor didn't do anything but offer some minor suggestions, and say that it WAS good enough. 8-( Anyway, one thing she did was try every trick in the book to get me to hold the pen/pencil "right"!
BTW I can do ok with my left, so with a little work I could be ambidextrous, but I favor my RIGHT! My mother was the same way, but favored her left.
BTW there are TWO "proper" ways to write with your left, but one with the right. The two "proper" ways with the left are one that MIRRORS the right but pushes the implement away from the hand, and one that twists the hand around to emulate the right, and pulls the implement towards the hand. When I tried to write with my left, I used the mirror approach. Moving the implement past the hands reach is, I think, harder though, so I didn't pursue it that much. Maybe if I learn arabic I'll do that, as arabic would make left handed writing easier!
