The Files

There are ten blank file folders on the table. On a slip of paper is written, “Please put these files in order.” I open the first file folder and inside it are ten more file folders. On another slip of paper is written, “Please put these files in order.” I am too scared to open the first file folder again, so I open the seventh file folder (in the first file folder). Inside are seven blank file folders, with a slip of paper which reads, “WRONG ORDER. PUT THESE SEVEN FILES IN ORDER AND THEN RETURN TO THE FIRST FILE FOLDER.”
