Reality is skewed into shades of gray. I doubt many of us can recollect every moment of our day yesterday without some embellishment or some omittion. However, I do believe it is wrong to sell something as fact when it is indeed fiction. A story that relates brutal human tragedies and marked as actual events encites stronger emotions in its audience than a work of fiction. It is not fair to make people invest a portion of their soul only to have the author state that "oops, I...um...that's not really the truth." It would certainly annoy me if I believed something was real, identified with it, cried tears, then found out that it wasn't real. I'd feel a little jilted and I believe there are others out there that would feel the same way too.
However, I do not remember where I heard or saw this, but it is possible for a person to believe a lie so much that the lie becomes truth within that person and would register as a truth on a lie dector. Also we all will recollect the same event differently since we would each hone in on different details. I suppose the whole truth and nothing but truth is subjected to point of view.
Anyway enough of that. I find it fun to read about ancient cultures. Some of them seem so fantastic it is as if you are in a fantasy novel. That's always fun. I'll stick with my fantasy except for class which kind of makes you deal with reality.
