So how are you going to sign a document if you can't write in cursive? Yeah I know "electronically signed". But I suspect some real documents will want pen on paper. My great-grandfather who was a mail carrier in southern Saskatchewan (starting before it was Saskatchewan) signed his name with an X. But I think he could read.
Anyway we've taught our 9 year old grandson to "sign his name". And he does so quite proudly on birthday cards and such.
I don't think our 7 year old grand-daughter does though. It's coming.
We were taught penmanship starting in the third grade. And your grade was determined by how straight, neat, and readable it was. I guess that's "run it's course" as well. Probably replaced by, "Lady Gaga and the Sociology Of Fame", or "How To Watch Television".
