Six years ago, on this day, a Tuesday, I was worried about the Chinese-language quiz I would be taking that morning, when I got into an elevator some time after nine. People on the elevator were talking about plane attacks and my first thought was either an accident occurred or a new action movie came out. The fullness of the horror was not imparted onto me until a little later that day. Let us take a moment to remember those who have passed away whether they were colleagues working at Windows on the World or rescue workers responding to the call of duty.
