Even after you leave someone, or they leave you, and you start your life all over again, pretending that you have moved on. There is always a piece of you that you have left behind with them. You can never get that back, even years together after you said you moved on. The moment you see them you are going to remember the first time you spoke, the first time you walked together. The way each other's fingers touched accidentally for the first time and the way you felt inside their arms. Each and every moment that made you weak. That is what the piece you had left behind of them is capable of doing to you.
