I too am a "grammar nazi" The one thing, well one of the things I cannot abide is the incorrect use of to,too, and two...Or worse using 2 to cover all your bases...I'd never mistake "pail steal blew" for "pale steel blue" either. I could appreciate critique like that. I even enjoy, or at least learn from having my typos pointed out. IF a character where to use incorrect grammar, I'd let my editor, or proofreader know up front...Though I cannot think of a context where a character's incorrect usage of grammar would come out in the narrator's spelling...Unless say a guy came in and filled out a job application, that was just full of inaccuracies. That would be an exception. Not the rule.
Thank you for your input however.
I know there are other writing forums out there. I just don't want to expose all of my ideas to people I do not know.
