I actually have a mild case of a condition known as Spatial Dysgraphia. It is a neurological disorder characterized by mixing of upper and lower case and print and cursive letters. My handwriting as a result is horrible. It always has been. In order to write properly by hand, it takes an extraordinary and time consuming effort. Basically, my hand writing looks horrible. That's it. My son's is the same way, and his doc thinks we both share this same condition, and were born with it.
