Once — a dozen years or so ago — I yawned my way past a politician giving a "stump" speech to the early morning commuters at my station. In fact, I had to side-step him on the narrow walkway.

Only then did I notice who he was: Naoto Kan — the current prime minister.

Of course he wasn't prime minister then. But he was still one of the brighter lights of Japanese politics, with his star clearly on the rise. So I did a double take on the walkway. How about that? Me and Naoto Kan, face-to-face! And I thought, "Naoto Kan! One day he might be prime minister!"
