(1)The half-empty coffee cups, still standing next to their plates, tell of a morning like others. And yet, that grey covering of dust that everything wears tells a different story: it tells of screams, tears, confusion, terror and blood.

(2)Now the restaurant in the World Trade Center will never again serve breakfast. And never again will all those people go there to eat or work --- those people of America whose faces have entered our hearts. So many people whose faces we associate with life and liveliness _______ tonight. So many words remain unsaid, and so much happiness has been destroyed. In their places are tear-stained faces. My generation has seen this. On Monday, a fight with my sister and a bad grade seemed to be the biggest problems in the world. Tonight, so many people across the country know that America’s pain is at its worst ever. We have read about World War II, and we have seen the black-and-white pictures. But to most students, that’s an event on a textbook page that would never happen today.

(3) After all, this was a time of peace and wealth --- the United States was powerful and successful. There would be no more wars, and we were lucky to live in such a time. But when those planes hit; when firefighters with terror on their faces ran among the parts of the buildings that had fallen; when people screamed for their family members; when history was unfolding before our eyes, in full, clear colour ---- then we knew the world had been changed.

(4) Everything that had happened in the past seemed to take on new life through September 11, 2001. And when they say this is the worst wound in American soil, I say, I thought this place was an empire. And I say, I thought this was a time of peace. And I say, I thought we were safe.

(5) Knowing how many human beings turned to ashes in a second, and seeing some jumps from the buildings, I know that my generation is growing up in a world where mankind can still be evil. But seeing those heroes risk lives among the castle-like ruins, and seeing the eager blood donors at the hospitals, my generation has learned that tears are allowed, that mankind can also be beautiful, and that the ghost of evil will never defeat the spirit of good.
