Writing is a form of communication that has evolved through time. Originally writing was nothing more than pictures on cave walls. Throughout history, writing has become more diverse and more complicated.
Today writing is an essential part of society. In past years, you could be a productive member of the community and be illiterate, that is not the case now. Many consider writing a form of expression, while others see it purely as a way to catalog data. Whatever writing is, though, it is undeniable that is essential to everyone's lives today.
