How do we remember to remember? That's a question I've asked myself often since my time on Duma Key, often in the small hours of the morning, looking up into the absence of light, remembering absent friends. Sometimes in those little hours I think about the horizon. You have to establish the horizon. You have to mark the white. A simple enough act, you might say, but any act that re-makes the world is heroic. Or so I've come to believe.
