Love, as the poet says, is like the spring. It grows on you and seduces you slowly and gently, but it holds tight like the roots of a tree. You don't know until you're ready to go that you can't move, that you would have to mutilate yourself in order to be free. That's the feeling. It doesn't last, at least it doesn't have to. But it holds on like a steel claw in your chest. Even if the tree dies, the roots cling to you. I've seen men and women give up everything for love that once was.
