Having contact sheets for all sorts of episodes in your life seemed to me intriguing and desirable. So much of my own history is beclouded by time, but a few sharp rays, in the form of pictures, falling upon a given day would resuscitate whole contexts. And from this archipelago of moments, scenes, episodes, you could see the larger tectonic movements of your life forming and unforming. You would be reminded of who you are. Or at least of who you were.
