For me, 9/11 affected me differently.
No one I knew died in the attacks, so in some ways I never had grief or a direct connection with the attacks. I was originally supposed to be taking one of my Drivers Ed training classes that morning, but it was cancelled because of it happening a hour after the first attack.
What I did feel, was a loss of a certain type of freedom. Like there was always going to be surveillance, always security. Where as a kid, pre-9/11, you could be out at night until your Dad threatens to beat your ass, just having fun, warned about STRANGER DANGER with white vans and dudes giving away candy.
Now it was like your shoes have to come off, you can't carry liquid. Just a highly distrust of its own citizens to prevent another incident like this again, yet I feel like the attacks itself were rare, and that the States isn't doing much work to keep an eye on local terrorists cells to prevent another OKC Bombing.
So as of today, I don't feel anything from the attacks, but the repercussions I feel and can tell what was then and what is now.
