Can you read and write cursive?

Yes learned to write and read it in 3rd grade.

As others have said reading it often depends on the penmanship of the writer. Some is easier to read than others. My own script writing is often chicken scratch the looks like a cross between a doctor's prescription for medicine and the order ticket you get from your Chinese take-out order. I can write it neater if I take my time with it, but often I am just jotting it down quickly. Trying to read what was written is the hard part. Particularly if it has been several days or longer since it was written since the memory of what I was trying to say is forgotten.

With the current trend of not teaching it in the schools in 2 or 3 generations any writing made from late 20th century or before will not be able to be read by anyone. Imagine students of American History studying the constitution looking at scans of the original document and not being able to read a single word of it.

I wonder how people get away with using print as their legal signature on official financial records and other documents.

I could read it before I could hold a pencil long enough to print a word. I don't recall being taught.

I never mastered writing it properly.

I guess so, but is that your "X" or my "X" or Charlie's X?
