Someone in a mosque once told me about the water behind people's faces. This water, he said, changed depending on what you did and what you believed and as you got older it began to freeze. The kind of life you led, whether you heart was full of love or joy or shrewdness or bile, all of this changed the nature of the water and, therefore, the look of your face. In this way, your face told the story of your life...
Maybe I'd been staring for too long, because she looked up. "What?"
"You have a very nice pond face."
