According to Muphry’s Law, which was formulated by John Bangsund of the Victorian Society of Editors (i.e. Victoria, Australia):

  1. if you write anything criticising editing or proofreading, then there will be a fault in what you have written;
  1. if an author thanks you in a book for your editing or proofreading, then there will be mistakes in the book; and
  1. the stronger the sentiment in (1) and (2), the greater the fault; and any book devoted to editing or style will be internally inconsistent.

Assume that every time a Word document is opened, its integrity has been compromised.
