writing allows me to express some emotion, something that I feel or see, or hear; and turn it into words. it helps me to put my thoughts in to order. it gives me memory of things that have happened in my life; a journal or diary etc. it allows me to write dreams, visions,
hopes, onto a page. it allows me to be creative. i have found it to be therapeutic in whatever form it is written in. it allows me to sing songs
written by me. there is so much that writing does. You have asked a very good question. It causes me to think about writing in more than just words.
