I vaguely recall a classmate in the first or second grade being forced to go righty. It's sad such mindless conformist idiocy was still being practiced into the early '70's.
I was a bit ambidextrous before the hand police caught up with me. I still favor the left hand on some tasks, but can't write with it.
