“Don’t judge a book by its cover.” This quaint piece of advice is older than anyone reading this, and in most cases has nothing to do with a book. It’s typically a preconceived opinion we have about someone or something that turns out to be dead wrong. There are a zillion examples of this adage like that big, mean-looking biker guy in your neighborhood that everyone gets out of the way for who is actually riding his Harley to go read books to sick kids in the hospital. Or, how about that ugly, old dog that no one really liked until he alerted his family that the house was on fire and actually rescued the cat. Yeah him. See what I mean?
