I was in school. 5th grade. Some kid came in talking about a crash at the World Trade Center, and I thought they meant the 'Socttrade Center' in St.Louis, where the Blues played. When they said New York I said 'oh', and didn't think anything of it. Next thing you know I'm getting called to the office. My mom in tears wanting to take my home. Only time she ever pulled me out of school. She was so afraid (which is unlike her, we played outside, walked to school, skinned our knees; I am fortunate to not have been raised by a paranoid helicopter mom!), she was afraid they would attack the schools next. Like many Americans at the time, I think she was mostly afraid of having absolutely no idea what was going on.
I remember watching it on T.V., we didn't turn the TV's off at home for 3 days. All night long the TV was on. Watched my mother fall asleep crying in front of the TV in her bedroom. I even remember going outside and seeing nobody out. No cars, no planes in the sky (I used to love to sit outside and watch the contrails from the planes), no kids playing in the streets. Everybody just wanted to be home, with their families.
