It Doesn’t Pay to Be the Grammar Police
You’re a writer; you know your grammar. Did you ever want to surreptitiously whip out your pen and correct a misplaced apostrophe or a typographical error (and there are so many!) on a sign? Don’t do it! Two grammar vigilantes were recently punished for fixing a sign. [lf]

UGH! I so want to fix the misplaced apostrophes and quotation marks. I will keep my Sharpie to myself.
“You’re a writer; you know your grammar.”
Beg pardon? Is it National Non-Sequitur Day already? In a long career as a copyeditor, I have no reason to suspect that this is true. None whatsoever.
And, to add two more cents, the self-important yahoos who defaced the sign got off easy.
