Do you have an unopened dusty copy of War and Peace or Catch 22 wedged shamefully in the back of your bookcase?
Take heart regarding your literary duplicity with this list from the BBC of the top twenty books people lie about having read (20% of which are by Charles Dickens)—and then slap those unread tomes on your bedside table, because 60% of those surveyed said being (or at least seeming) well-read made a person appear more attractive. I guess that may be the motivation for the lies.
This list is for the UK, but I have a feeling people are bluffing about reading these books in the US as well…
