I am a writer. So I write. I write for you. I am your medium. my writing does not always reflect me but you can use me if you need to.
I let you say "man that girl is crazy"--when you really mean you.
I write what I see and I feel it for you. I ache through your pain. I dance for your love. I cry for your sorrow. I boil for your fury.
and I write it all as "I" so that you can admit to your feelings through an outside party.
