But, we're still here. 9/11 didn't destroy America. Instead, it gave us a reason to want to exist, and made us temporarily aware of how much we rely on the kindness and sacrifice of others to keep the gears going.
Today, though, is not a day to think about how we've changed. It is a day to remember those that died and those that sacrificed their lives doing a job that we take for granted every single day. We should be ashamed of ourselves for ever forgetting how important firefighters, police officers, and even our soldiers really are in the grand scheme of things. They do for us what we can't do for ourselves.
So, today, we should remember them. We should give them some measure of thanks for their willingness to spill their blood and risk their lives on our behalf. And we should remember those innocent people who were ruthlessly murdered.
