I don't know why, but when I write, I prefer blue ink over black ink. It seems like a funny preference, but black ink just doesn't seem to write as well! ;-) I don't really like to write with a pencil either. Not even a mechanical pencil. Oh, and I don't like gel ink. The gel ink tends to make my writing sloppy.
Handwriting? If I concentrate and take my time, I have good handwriting. Notice, I said if I take my time. If I don't take my time, my handwriting is still readable, but not very neat. I typically write in cursive, though sometimes I print. It just depends on what I am writing. My legal signature combines both printing and cursive: the first letters of my first and last name are printed, the rest is in cursive.
