1. That things

The realization that feelings never really completely go away. The truest form of feelings, they linger, invisibly carved into your skin, your heart. The eat you away inside. They burn into your mind, until one day you find yourself remembering scenarios that never really happened or creating non-existent events in your mind. And that's when the real hurt consumes you, in the moment that you realize that they never will. That things change, people and feelings and what-not, that things never really last forever, and that when they expire, your left ruined, tainted with feelings of nostalgia and pain, or with, something worse; yourself.
