For the love of all that is sacred. If you ever find yourself uttering the sentence, "Oh, you're just like [character name] in [book title]!" - STOP.
Just stop. Take a deep breath and step away from your library. No, the real live person you are talking to is NOT just like Character Name in Book Title. They may *remind* you of this or that memorable character, and perhaps the similarity may even give you some insights into their personality. But the person you are talking to is a unique human being, not a character in a book. They have their own story to tell.
