Book excerpt: Originally published in 1977, this book was the basis of numerous other books written on the languages of love. Saying "I love you" is not the only way to express love. You can also spend time together, help each other, give gifts, or bring out the best in your mate. In fact, Judson J Swihart says there are eight languages of love. And yet there's a problem: these languages are often not understood. So the author helps married couples unravel the complexities of saying and hearing "I love you."
