As people continue to fight for freedom in other countries, the US grieves for its loss of innocence on this day.
I vividly recall my bewilderment that day:
I've never seen my dad cry before.
He was furtively wiping tears from his face, recalling his friends that worked in the Towers as we watched it burn from half a world away. It looked like a bad movie special effect, only this was real.
It is shameful, but it's true: My only thought that day was that I'm glad my dad was home after 8 years of living in New York.
I can't pretend to know how Americans are feeling, however - I'll offer to hold your hand in respect and silence.
I'll never forget too.
