It's is up to you to decide what is truth and what is imagination.
What I write may be whole-hearted truth, or it may be pure fantasy. It may be extreme exaggeration, or I may leave out half the story. It is all up to you. It is my job to tell these tales, and yours to find the truth in them. You may be right, you may be wrong, it really doesn't matter. You believe what you choose to believe.
It's what we all do anyways
