I want to add my own thanks to those already chimed here.
It is the strangest feeling to be so utterly sad, and so completely touched and proud all at the same time.
This was not something that happened to the US alone. It happened here, but there were people from all over the world in the twin towers, and likely a few at the Pentagon as well.
The world grieves the loss, and those of us at ground zero are heartfelt touched by the connection this great tragedy has brought to the peace loving people of the world.
From the bottom of my heart, my brothers and sisters,
Thank you!
