I was in 4th grade at the time. All the kids at my school were leaving early, and none of us understood why. Finally my teacher said some building was bombed, but was very vague about the rest. Finally when we found out from other kids, I was terrified because my both of my parents worked in Manhattan. Fortunately, my dad picked me up early and then my mom was able to make it back home. That day was seriously the worst feeling in the world.
