Probably all lies

One day I inhaled so hard I become two dimensional. Ever since I'd slid through the cracks in the world, unnoticed. This probably isn't true.
The real truth is the real me left long ago. I was originally his shadow but we did a deal to change places. It was difficult learning to walk, learning to give the impression of depth, of an extra dimension. But I managed enough to fool most, but for some reason it's easy for me to slip by unnoticed, to become a shadow again if I need to. The real me ran away with a shadow girl and left me alone. It's another story of how I found a shadow of my own, or maybe this is all a lie.
No, I'm really a powerful sorcerer, presently in this form to avoid my enemies. While not as strong as me individually they are numerous thanks to numerous indiscreet acts and a lifetime as doing as I fucking well wont. I avoid using magic unless I really must, maintaining one protection of arcane anonymity. As vampires supposedly do not show up in mirrors, which would be a damned nice trick if true, I'm statistically invisible. I don't show up on file. I am not a demographic. I figure after one or two generations, nothing to one possessing my abilities, I'll be able to regain my former place in the world. So long as I remember who I am. Unless I'm lying.
Which I am. The true truth is I'm no one in particular, and lazy. No really cares whether or not I'm on record for this or that and I'm not one to press the issue if it means I have to do less. I dislike filling out forms not because I don't want to reveal things about myself, but it's time that could be better spent contemplating my belly-button lint. Which is all true. Unless it's not.
