When you write, you can find things out about yourself that you never knew. Like how you really feel about someone. For example, if you write about small occurrences with a certain someone, and how you feel before, during, and after each occurrence, you should see a pattern emerging, and you�d realize how you really feel, rather than how you thought you felt. Or, perhaps writing might show you what you truly want to do if you�re bored. If you write about how you feel at the moment, sometimes possible solutions to your problems come flying to the front of your mind, and out through your finger-tips, with out you realizing it for a while.
It can also just be pure relaxation. Fumigation, perhaps is more the word I�m looking for. When you can�t find any solution, and all hope is lost, just to sit down and write about how you feel, to put it all on paper, can soothe certain wounds. It makes you feel light, and wispy just to "get it off your chest."
Writing. A joy many should have, and any could have.
