The thing is, "Martin Gibson" does exist--he is more "real" in cyberspace than the person who created him--and the person who created him doesn't realize that "Martin Gibson" has already taken over his "real" life in subtle ways--

If you don't believe me, "Creator-of-Martin", think about how much of your real life you give up to "Martin Gibson" every time you write a post, and then come back later to see how people responded to it-

You have already said that "he" isn't you, and that you walk away to be a very differerent sort of person in your "real" life, but the fact is, you keep coming back to be him, again and again--
