I don’t know...to me, reading cursive and writing it are (to me) two different things.
Writing cursive is akin to knowing a language.
Reading cursive is akin to simple interpolation-kind of like knowing Spanish, and being able to noodle out the meaning of something in Italian or French that you don’t know, simply because you know Spanish.
Cursive can be so variable, but...after your figure out how someone makes their “e” and “i” and so on, then you just hit a word you can’t immediately figure out, and you interpret it contextually, and you have that figured out.
I guess I completely understand why people don’t write it, I just don’t understand why someone can’t read it.
Cursive is actually far less effort than block printing. You don’t have to start, stop, lift the pen, drop the pen, just a loose grip and light wrist action will do. I’m just old enough to have been taught cursive and to have used it through school prior to college, but upon graduation emerged into a world adopting desktop computers. I was also trained to use a stylized block print on sketches, proposals, hand-drawn graphics and such in design school.
