For years, I thought Black Friday was named for the rudeness and misbehavior of day after Thanksgiving shoppers. I didn't realize it was for shop owners who were now solvent and "in the black" after 11 months of being in the red.
It's a lot like writing. The majority of the time you use a red pen to hone a story to a fine edge. Then, after many revisions there is only black ink, no more rude red; the piece is polished to perfection. It becomes Black Friday or Black Tuesday or whatever.
Like finding a great sale, satisfaction reigns. Send it to an editor and hope for green.
