C.S. Lewis - автор Хроник Нарнии
"To love at all is to be vulnerable. Love anything and your heart will certainly be wrung and possibly broken. If you want to make sure of keeping it intact, you must give your heart to no one, not even to an animal. Wrap it carefully around with hobbies and little luxuries... lock it up safe in the casket or coffin of your selfishness. But in this casket - safe, dark, motionless, airless - it will change. It will not be broken; it will become unbreakable, impenetrable, irredeemable... The only place outside heaven where you can be perfectly safe from all the dangers of love is hell!"
