Alexander Christofi, a book publishing editor (!), took to Twitter to confess to a ghastly crime: he cuts his books in half through the spine in order to make them physically smaller and therefore easier to carry around and mutilate further in his spare time.

SparkNotes, which operates a very funny Twitter account that you should follow, had the best response:
