You know what's scary about this world? It isn't everything. It is anything. The knowledge that anything is possible at any given moment. The chaotic unpredictability of it all is frightening. There's always a chance the worst possible thing could happen and you wouldn't even see it coming.
Some people have avoided that though just through sheer dumb luck. It's the kind of thing that affects everyone differently. Some people take it as divine intervention and other see it as just a happy coincidence. Whatever the case may be, it will be the kind of thing you will carry with you for the rest of your life.
