I've changed because the world changed that day.
However, it sadly seems that the world doesn't have a good memory. The world no longer remembers very well the evils of World War II and the holocaust, or the bombing of the US troop barracks, or the attack on the Cole. And now, though we stop and remember today.... that memory, and the emotions the world felt that day are sadly slowly fading.
I'm very much with Doug. We NEED to remember, and remember the resolve the world felt that day!! Without that resolve we're still in great danger of seeing it all happen again.
