A nice little excerpt from Zan Perrion's "The Alabaster Girl":

A boy looks for all the ways that he can impress a girl. A man looks for all the ways that she can impress him. A boy seeks to maximize the way he appears in her eyes. A man seeks to maximize the way she appears in his eyes. A boy wonders what she thinks of him. A man wonders what he thinks of her. A boy asks himself, "Where is she on a scale of one to ten?" A man asks himself, "What is beautiful about this woman before me?" A boy asks himself over and over "Does she like me? Does she like me?" A man asks himself over and over, "Do I like her? Do I like her?" A boy is in his head. A man is in his heart. A boy observes himself. A man observes her.
