An observation by a fellow bar patron.

After being asked what book I was reading at a bar the other week, I showed a fellow bar patron the cover of Ursula K. LeGuin's "A Wizard of Earthsea."

"Oh," he was like, "Is that part of a series?".

"Yeah," I was like.  "How did you know?".

"Because it's short," he was like.  "And also, all books about wizards are like that.  There's always three or four."
