In first grade they taught us to print. Then in second grade they taught us cursive handwriting. I caught on, though from the start my handwriting was messy. Also I didn't much care for all the loops and whirls in the standard style of handwriting we learned in school. Writing all those loop-de-loops drove me crazy.
So, starting in fifth grade, I began experimenting. Designing my own style of handwriting. Lose those loops. Try out different styles of letters and ligatures. It took me a while, and then it took me a while longer to become adept at writing in a strange new way. But by the time I was in seventh grade or so, I was very much at ease with writing in a self-designed style which bore little resemblance to any cursive mode taught in school.
A handwriting of my own. It mutated over the years. For a time in my teens, very messy. Here and there, a letter changed: I can still remember the day, late August or early September of 1982, when I changed the way I wrote capital L.
What emerged by age 20 or so was a style of handwriting that looks something like the chrome lettering you see on automobiles. Still somewhat messy, what do you expect from a lefty? Two different ways of writing small f, depending on context. Two different styles of small x. At least five or six radically different ways of writing small t. "O" in "of" written unlike "o" in any other word, clockwise instead of counterclockwise.
I see other peoples' handwriting, sometimes they depart more or less from school-taught handwriting. But rarely do I see anyone who has departed as far, or as deliberately, as I. Part and parcel of living in a self-designed world of my own.
Oddly enough, I continued to use the old school-taught writing alongside my own style of handwriting, on into my mid 20s at least. Often wrote in the school-taught way when I was writing school assignments, or sometimes for others to read. But it's been years, and I doubt I'm fluent in the school-taught handwriting any longer. It's my own style of handwriting or nothing nowadays. When I'm not using the keyboard, which has become ubiquitous in the lives of many of us as never we once would have dreamed.
