...your characters are a great way to cure loneliness. I was listening to a review about the new novel "Mr. Dickens and his Carol" and it's said Dickens would hole up in his room and BE all the characters. He'd talk in their voices as he wrote. So out loud he would say their lines, dialogue, whatever you wish to call it. People would fight, talk back to one another, profess desires, cry... they would be real.
That's about the only way I can legitimately say I have something in common with Charles Dickens. I've always said my dialogue out loud while I write. And I notice if what people say whether in a novel, in a play or on a screen sounds false. I wonder if the writer is really in touch with his or her characters. I feel like the writer is using the characters but those characters are two dimensional mouth pieces for his or her ego and it drives me nuts. "People don't talk that way!" is what I tend to think and it takes me out of the story.
Your style may not incorporate natural dialogue and that's fine. There's room for a lot of voices in the world. But your character's voices should be real to you. If they're real to you that will come across in what you create. And it makes writing a hell of a lot less boring.
Say it out loud. It's kind of fun. Personally I think that's why I love my catty characters. I get to be a dick without being a dick in the real world. It's very satisfying.
Hope this helps and good luck with your writing!
