I watched a show remembering that day all those years ago. It was about some of the survivors and the heroes and the horrors and the love.
I remembered that moment of disbelief as I stared wide-eyed at the TV screen.
I talked to my son about it and about the world, the good that exists in people and a bit about the bad. As the last story flashed across the screen and I sobbed at what they said, he hugged me. Then he hugged me again.
Because that's what we need to remember.
