"And then come back and say what it was like. Did you feel fidgety and impatient? Did writing feel too slow for your thoughts, or did it slow them down in a pleasurable and even fruitful way? Holding a pen to me is like holding an eager dog on a leash. Has your handwriting deteriorated from disuse, too?"
Well, I'm not going to do this, because everyone I know would either think it was crazy to write and mail a paper letter or feel oppressed by the implication that now they need to handwrite a letter.
But I do still use handwriting, and I often prefer it when I'm writing notes for my own private use — that is, not composing something for readers. I prepare for class by writing notes in the margin, and I teach the class using those notes along with the assigned text. I feel that the handwriting has a spirit to it that helps me a lot. It's not something I use to show my personality and feeling to another person, though I understand why handwriting conveys that. It's something that, for me, remains more closely interwoven with my continuing thinking about a subject. It's less final and it works better to keep me connected with the original text. Marginalia — it means a lot to me.
