I approach stories as a private educational enterprise: I want to learn about something. I teach myself through research, reporting, and thinking, and then, when I feel like I know the story, I tell it to readers.

Everything rational and sensible abandons me when I try to throw out photographs. Time and time again, I hold one over a wastebasket, and then find it impossible to release my fingers and let the picture drop and disappear.

You may never learn the names of any of the people you talk to in a dog park, even after many, many hours spent there with them, and many hours of conversation. But if - knock on wood - anything should ever happen to your dog, these nameless non-strangers will rally, sympathize, offer to help, and hold your hand. I know this from experience.

In an interesting inversion of status, the reigning breed in the dog park these days is the really-oddball-unidentifiable-mixed-breed-mutt-found-wandering-the-street or its equivalent. The stranger the mutt the better; the more peculiar the circumstance of it coming into your life, the better.

I went to a football school, which meant that I went to a university that served up education and was simultaneously operating a sports franchise.

When I heard about the Microsoft Kinect, though, I felt an urgency rising in me. A game you played without touching any machinery? A chance to wave your hands around, Minority-Report style, and move things around on a screen? This sounded like almost too much fun, with gadget-y pizzazz that sounded astonishing.

It seems that half the point of being in Miami Beach - particularly the northern end of South Beach - is to be observed by people-watchers like me, and the display along Ocean Drive during my visit was, as always, sublime.
