Most people have today off. Most people that aren't writers. We don't ever really have a day off. Even when we aren't writing, our brains are still cataloging real-life events that might work in a story someday, creating new characters, thinking of titles for books not even plotted out, eavesdropping on interesting conversations when a curious line of dialogue catches our attention.
We're writers. We're always at work.
But for the rest of you...have a great day off!
