There is a gargoyle on the northwest corner of the tower who has been making the same expression for four hundred years. I asked the Archwizard what it means. He said: "That is what your face looks like when you have been watching humans make the same mistakes since the Renaissance and you cannot close your mouth because you are made of stone." I understand this gargoyle now. We have an arrangement. I do not clean the moss off him and he does not judge me for talking to birds.
