“We always look for the signs we missed when something goes wrong. We become like detectives trying to solve a murder, because maybe if we uncover the clues, it gives us some control. Sure, we can’t change what happened, but if we can string together enough clues, we can prove that whatever nightmare has befallen us, we could have stopped it, if only we had been smart enough. I suppose it’s better to believe in our own stupidity than it is to believe that all the clues in the world wouldn’t have changed a thing.”
