Though the remains of the original building are gone, evidence of that day still stands:
On the outside fencing of the memorial, people from all over the world have left trinkets and bits of their own lives as tributes to those who were lost.
This is a picture of my son, looking at the objects on part of the wall. Part of me is sad when I see this image because it represents the intersection of my sweet little boy and the reality of this world.
The other part of me hopes I can teach him to make it a better place.
