September 11th - where were you?

I had only just started Middle School at the time (at age nine), so the majority of the story pretty much passed over my head and childhood innocence made me think it was just a terrible plane crash. As I got older, I learnt it was more than that, but it's still a very tragic occurrence. I talked about my thoughts on 9/11 on my YouTube channel two days ago and it really did make an impact on not just America, but the world.
