Of the loss.
In this way trees can't ever let go of love,
If trees do, when someone they knew dies. When the branches that were touching and entwined touch no more, a part of the tree forever dies.
In this way, I think, trees have more integrity. They live with the loss and the passing by of cars and people, traveling perhaps, a long distance on vacation, the way they lived with the trees that were once there. They continue to grow, up and around the lack.
