Sometimes I get poetry and prose mixed up in my head, and I end up writing something like this.
Every story ever written is made up of the same twenty-six letters, just in different combinations. That’s a finite number. You can’t just create more letters – at least, not letters that will make any sense to anybody. So every story that ever is, was, or will be is shackled by those twenty-six elegant little restrictions.
Which means that there is only a finite number of stories.
