" They can’t. They’ve been changed. There’s no going back. This is the fallacy of the good old days: not only are they gone and never coming back, they never existed in the first place. That’s the horror of existence. Change happens whether you want it to or not. Existence is by its very nature progressive. It continually asks, So now what? How are you going to live through this? How is anyone going to live through this? "
