I remember back in 1975 our school was already teaching phonics writing if I remember the the course name correctly.
You used the phonetic version of words. Like Slo for slow, rite for right. Probably a precursor in the stuff you see typed out on phones now.
I broke my arm when I was 6, and had to learn to write right handed. I'm one of those odd balls now. I write, eat, and shoot left handed. Everything else like throwing, bowling, etc. I do right handed. And my cursive is just as bad left or right, so I print.
As for teachers today, I wouldn't wish that on anyone. They have a thankless job. Poor funding, unruly children, parents, if there are any, who don't give a flying flip, silly standards, no child fails rules. Sport stars who are treated like gods, who can do no wrong. Oh well, I taught my kids to be respectful, speak correctly, be polite, and it did them well.
I deal with the public every day. And what I see, in customers and my employees has me shaking my head as to how these folks made it this far, yet alone how they will make it the rest of their lives.
