You know whats fucking scary? The fact that I could literally change my life at any moment. I could stop talking to everyone that makes me unhappy. I could kiss whoever i want. I could shave my head or get on a plane or take my own life. Nothing is stopping me. The entire world is in my hands, and I have no idea what to do with it.
Of course, you never really forget anyone, but you certainly release them. You stop allowing their history to have any meaning for you today. You let them change their haircut, let them move, let them fall in love again. And when you see this person you have let go, you realize that there is no reason to be sad. The person you knew exists somewhere, but you are separated by too much time to reach them again.
