Who Made Whom?

Lean closer, dear friend, my secret to hear. Speak softly, Mr. Know-it-all is near. I am unsettled by his depiction - a poetic character of fiction. It is I who created that sad man, not so believable, but I did try. Admittedly, he's poorly drawn, that guy. When he cares, he acts like he doesn't. If he says his heart's in it, it wasn't. You'll soon forget him. He will disappear. So depend on me. I'll always be here.
