Nothing; There is no guarantee of anything in life. Especially safety. You never know when some freak will walk around the corner and smash your balls in with an ax. So live life well. After all, it might be tomorrow that that one kid finally does act on their threats. It might be today that a demon really does appear in your mind and you shake their hand. It really might be yesterday where you woke up and realized that your life really was a disaster and that's the reason you ate all of my nerd's gummy clusters. Well screw you! I got back at you by paying the universe substantial sums of money so that your life, for the next 2 and 9 quarters years will be a miserable train wreck of emotions and feelings and... I just realized I monologued my revenge plan to you. OH WELL.
There's no way you read all of that.
Guess You're marked safe from reading it.
