Because, this isn’t the internet or anything. No one will ever know. 
OK, so maybe I’m a little crazy.
But, the point is, I know I’m not the only one who has a shameful little secret, something that, as a writer, I am embarrassed about, and rightly so. You too? Oh good. Well, I’ll show you mine, you show me yours?
I don’t like Tolkien.
That’s right. I’m a sci-fi/fantasy reader and writer and I don’t like Tolkien’s books. I’ve said it. I feel FREE!
(Don’t get me wrong, the movies kicked serious butt. And if the last man I ever see in my life is Orlando Bloom as Legolas, well, I’ll die a happy little writer.)
See?
OK, your turn. What’s your writerly sin?
