In the days of cursive communication my mother used to say that your penmanship was the first impression you would often make on a person.
Then thank heavens for the death of one superficial standard that people are judged by!
Some of us have hand-eye coordination issues that make our writing less than perfect but don't affect us in other areas that we can be productive in.
I had to go to summer school as a child for my writing problems and even as an adult its somewhat sub-standard. However my grades allowed me to graduate near the top of the class.
Yep, because something has to be, whether one likes it or not. And penmanship tells much more about you than the color of your socks, as some would prefer.
