I was a teacher on 9/11/01.
I dropped my students off at their P.E. class, stopped by to say hello to the school counselor and was greeted by his television airing the horror of that day. I practically ran back to my class to turn on the television. I watched for 50 minutes before I had to go pick up my students.
I spent every spare minute for the next three days glued to the TV. My wife and my mother both told me I had to stop watching, but I couldn't. I wanted to re-enlist in the Navy to make some sort of contribution to paying back whoever was responsible. My wife wanted no part of that with a 15 month old baby and another one only 5 months away.
The world stood still while firemen, policemen, military personnel and numerous volunteers dug in the rubble for survivors.
People said our country would never be the same. Sure, the events of 9/11 scarred us individually and as a nation, but it didn't take us long to get back to the status quo.
