In America, cursive letters don’t look like block letters. Thats the point of this entire post. Kids can’t read it because it’s almost like learning a second alphabet. If they were one and the same why would anyone have trouble reading it?
In America plenty of people write regular print fluidly in one, or fewer pen strokes. But that’s not the same thing as cursive in America. Cursive is a very specific script of very extravagant, stylized letters.
I was taught to read and write cursive in grade school and now as an adult I literally can’t, because I’ve forgotten.
