Are you a writer?

 A friend had me read his book draft.
It was good.  I would've checked it out at the library and even finished reading it.  It was that interesting and that much like a real book.
I thought, "Damn.  What have I been doing?  I could write a book."  

Then he told me he had worked on it and refined it for five years.
"Oh," I thought.  "Never mind."
