“ But we know that we are no longer the same, and not only know that we are no longer the same, but know in what we are no longer the same, you wiser but not sadder, and I sadder but not wiser, for wiser I could hardly become without grave personal inconvenience, whereas sorrow is a thing you can keep on adding to all your life long, is it not, like a stamp or egg collection ”
