Back when I was younger and had to hand write everything, I developed an odd bug in my handwriting. If a word ended with the letter “d” or “g”, I would consistently write the other letter. It didn’t matter if I was printing or using cursive. It would happen every damned time, and I’d have to scratch it out and correct it. Oddly, although lowercase “d” and “g” are, roughly, vertical mirrors of each other, I did not have the same problem with lowercase “b” and “p”. And lowercase “q” never entered in there. Just “d” and “g”.
Later, when I learned to touch-type … I kept doing exactly the same thing.
With typing/keyboarding, I eventually trained myself out of the mistake/habit. In my handwriting, I stopped using cursive for anything other than my signature 2-3 decades ago, in favor of the printed, capital block letters I learned in my high school architectural drafting class. Easier for everybody to read. On occasion, however, I’ll decide to write in cursive, or use printed lowercase letters to write down an e-mail address for somebody, or when I need to write down a password that has a combination of uppercase and lowercase … and BOOM! There I am, flipping my d’s and g’s.
Could this be a mild form of dyslexia?
