To spend twenty minutes eating lunch outside is to be fully immersed in a world. An aquarium of people. "Have I said it before? I am learning to see," Rainer Maria Rilke wrote in his classic The Notebooks of Malte Laurids Brigge. "It never occurred to me before how many faces there are. There are multitudes of people, but there are many more faces, because each person has several of them."
