On my Dad's side of the family, there's something of a preponderance of lefties, excepting my Dad and his seven siblings; after Grandma, it apparently skipped a generation, showing up again among the cousins with more than was statistically usual. I was one of them.
When she was little, Grandma endured a lot of abuse from parents and teachers, trying to force her to be right-handed. This made her an aggressive advocate for lefties among her grandkids. Coming to Texas to celebrate Thanksgiving with us one year (1970, I believe - the same year I had to evade a pair of teenagers/young adults trying to abduct me walking home from school, as I have related to the DL), she misinterpreted my Mom's table settings with silverware to the right of the plate as evidence of an effort to change my handedness. It wasn't, but still a confrontation broke out.
My Mom always sought to accommodate my lefthandedness, sending me to school with a pair of lefty scissors with the green rubber handles. My first grade teacher was having none of it; the scissors kept disappearing from the vinyl zipper bag in my binder. Eventually we realized it was the teacher doing it when I was out with the other kids at recess. There were a lot of issues with her, including her pulling my hair, slapping me around, and knocking me out of the desk. I've no idea what her actual issue with me was (the fact that I was lefthanded? Seems too extreme, but who knows?), but she concentrated her physical and verbal abuse on me, and threatened the other students that if they told anyone, she would do the same to them. Crazy bitch.
That particular school cultivated a weirdly abusive ethos; the principal was rumored to possess an electric paddle to be used on students. Indeed there was, in his office, hanging on the wall behind his desk, a wooden paddle with wires strung to plugs protruding from its edges. Looking back on it, I don't believe it was in any sense functional, but seemed to be just for show, but the fact that teachers and the principle were themselves responsible for propagating the rumor is very odd. My parents removed me from that school, and had to do a certain amount of negotiation with the ISD to permit me to attend a different elementary school.
The next one was just as backward and savage; on the first day, a little girl accused me of having said a bad word, and I was made to stand with my face to the wall in a corner at the front of the class for fifteen minutes, hands behind my back, holding a dime against the wall with my nose. If the dime fell to the floor, the teacher doubled the time. I didn't last a week there.
The third elementary school had to be the last; no more district shifting around. My second grade teachers were also quite abusive; lots of slapping, pinching, and hair-pulling. This bullshit seemed to stop when I reached the third grade, and I never experienced it again; it was as if there'd been a sea change in the way classes were conducted.
Sorry, I've digressed quite far from the subject of handedness, but I'm curious: did anyone else experience that kind of abuse in schools from the early 1970s?
