Khaled, my first teacher, was the kind of man who carried his past in the temple fires of his eyes, and fed the flames with pieces of his broken heart. I've known men like Khaled in prisons, on battlefields, and in the dens where smugglers, mercenaries, and other exiles meet. They all have certain characteristics in common. They're tough, because there's a kind of toughness that's found in the worst sorrow. They're honest, because the truth of what happened to them won't let them lie. They're angry, because they can't forget the past or forgive it. And they're lonely. Most of us pretend, with greater or lesser success, that the minute we live in is something we can share. But the past for every one of us is a desert island; and those like Khaled, who find themselves marooned there, are always alone.
