Me Own Opinion
Question: What’s the only thing worse than turning your theme into a sermon?
Answer: Having no theme, at all.
Here is the best attitude on themes: Whilst I’m amusing readers with this story, I’m going to painless introduce a new idea. My theme will not be a lifeboat bobbing on the waves, but an insidious undertow that will drag the reader farther and further away from the safety of familiar shores, until they understand the message. It will not be a hidden code, nor will it torpedo them into the Deep Six. It will remain below the surface and my message will slowly swamp over the deck. They will never know what sank them, until The End.
