"Not everybody, however, has a genuine sense of humor. That calls for an altruistic detachment from oneself and a mysterious sympathy with others which is felt even before they open their mouths. Only the person who has also a gift for affection can have a true sense of humor. A good laugh is a sign of love; it may be said to give us a glimpse of, or a first lesson in, the love that God bears for every one of us."
