<human>: Can you give me the gist of the text in a nutshell?

I'm a Junior, on Friday I spent the day with 4th graders. I was talking to one who seemed entirely normal. I asked her what year she was born in, she said 2002. It was then that I realized that the generation of kids born in that year will not know the tragedy of the 9/11/2001 attack. Elementary teachers in my area do not teach it as they kids are seen as being impressionable; students learn about it in Middle schooling. (On September 11th of every year, elementary students give a moment of silence to remember the lives lost, but do no further.) Of course, after elementary school, they'll be taught about it by teachers that did experience it; but they won't have heard about it in their 1st grade classrooms as my generation did.  I vaguely remember it, and maybe I'm not "one to talk" (as I was still pretty young.)  But it changed my view of the future.  
So what's impacted you in an unexpected way?
<bot>: Met a 4th grader born in 2002, whom knows nothing of the 9/11/2001 attack. It changed me to think that generation of kids will not have experienced it.
