Remember that episode of Seinfeld when Kramer befriended the Japanese tourists and had them sleeping in drawers? Well, just this morning, a whole crowd of what looked to be Japanese tourists entered the lobby of my building. They stared in at me unabashedly, even as I stared back. Then the whole bunch of them numbering at least 27, piled onto the elevator, squeezing in like a group of college kids into a phone booth. Maybe it was part of the new "flash mob" craze. I never did see them come back down.   ¶ 5:03 PM
