Re: Farther vs Further
If you are dealing with someone like me, who had a huge harridan for an eighth grade English teacher, farther is used only for distance, and further for conceptual extent.
I don't "correct" people who mix and match...it just doesn't matter enough. I like precision in language, when I'm not striving for vagueness, so I do distinguish between these words.
