I was in high school, senior year and in my gov't and eco class. I will never forget what happened that day; while I personally did not loose anyone there were many kids from my school that lost family on that day.
I actually just came back in from the rain; the company I work for hosted a re-dedication for the Freedom Stone we donated years ago for the cornerstone at ground zero.

Aside from the rain it was a nice ceremony and really brought back memories. There are many policemen and fire fighters that are still struggling with their health due to the service they put in on that day.
I think its important we all remember and honor those who lost their lives and the families they left behind as well as those who gave their services in the rescue efforts.
