What is Writing?

What is writing, Is it life? Immortalized in strokes of pen and keyboard? Is it the author, proudly displaying scars? Dripping ink-ridden blood all over used-to-be-white pages? Is it a hopeless cry screaming out? Begging to be remembered to be passed on. Is it a guide on how to be human? Emblazoning us with hope, choking us with despair. Is it dreams, or nightmares? Filled with worlds that seem so real. Is it a message, adrift in a sea of letters? Carrying directions, or a dire forewarning? What is writing? Would it be simpler to ask? What am I?
