Smile at each other, smile at your wife, smile at your husband, smile at your children, smile at each other. It doesn't matter who it is, and that will help you to grow up in greater love for each other. 

Many Americans are familiar with The Little Prince, a wonderful book by Antoine de Saint-Exupery. This is a whimsical（古怪的） and fabulous（难以置信的） book and works as a children's story as well as a thought-provoking adult fable. Far fewer are aware of Saint-Exupery's other writings, novels and short stories.

The smile, the unaffected, unplanned, natural connection between people. I tell this story in my work because I'd like people to consider that underneath all the layers we construct to protect ourselves, our dignity, our titles, our degrees, our status and our need to be seen in certain ways―underneath all that, remains the authentic, essential self. I'm not afraid to call it the soul. I really believe that if that part of you and that part of me could recognize each other, we wouldn't be enemies. We couldn't have hate or envy or fear. I sadly conclude that all those other layers, which we so carefully construct through our lives, distance and insulate us from truly contacting others.

I've had just a few moments like that. Falling in love is one example. And looking at a baby. Why do we smile when we see a baby? Perhaps it's because we see someone without all the defensive layers, someone whose smile for us we know to be fully genuine and without guile. And that baby-soul inside us smiles wistfully in recognition.
