I was in high-school when it happened. I remember after first hour, on my way to second hour, a buddy of mine, Bobby, came up to me in the hall and told me he heard an Apache helicopter had shot missiles into the Empire State Building.
There was an uneasy feeling throughout the school, but no one really knew what was happening yet.
My third hour class was Current Events. The teacher in there said that something terrible had happened and we were going to go to the cafeteria to watch the news. There were three other classes in there and the dozen or so televisions were turned to various news channels.
It was silent. I don't think anyone knew what to think or expect. Some people were crying. Less than ten minutes after arriving in the cafeteria, the first tower fell. A few minutes after that the principle came in and told all the teachers to take us back to class. I guess this was their way of censoring possible live events that would be upsetting.
It didn't matter. Every teacher (except for the math teacher I had) turned their televisions on. We watched the news all day. Really, after the second tower fell, there wasn't much "news" other than the survivor here and there and most the time, the chaos of the day caused that to be reported late or just rumored.
That night I had to work at Four Seasons Pool. No one came in that night. We just watched the 10" television as they replayed the same clips over and over again. Everyone took turns watching the front of the store while everyone else went and filled up gas, assuming prices would skyrocket. If I remember right, they did skyrocket that night while we were all taking turns. Going from $1.01 to somewhere around $2.50. They've not come down since.
I guess all we can hope for today is that the violence in the world can someday turn to peace. That needless death can cease. But as long as there have been humans, there has been war.
