Who Am I?

No, seriously....Guess. A little experiment in sociology as it applies to literature.

I am the storyteller,

weaving dreams,

And the lawyer,

telling lies.

I am both good and evil,

kindness and cruelty,

 Your reliable friend,

And your bitter enemy.

Once I was you,

and once you've been me too.

So I ask,

who am I?

Author's Note

Many believe that a writer's identity is always present in their work, even when they switch perspectives and even gender in their narration.
I basically want to see if you can accurately describe me based on my writing, despite never having met me. You can use this poem or any on my site.
