Accidental Pierre Menard

When he finished reading Borges’ story “Pierre Menard, Author of Don Quixote”, he shook his head and chuckled. At his desk inside, he began writing. Each day he wrote – something new every time he sat down. Today the story took hours to work itself out, like a snake unkinking and stretching in his mind.
The next morning his friend called.
“Why did you send me that story again?”
“Again?”
“You wrote that months ago.”
“No, I wrote it last night. It took me hours. Wait... I remember! Did I really write the same story twice? What are the odds!”
