I have two friends in Rome who I refer to as San Rocco and the dog. Iconography of San Rocco almost always shows him with the dog that tradition tells us helped nourish the saint back to health. And, this became a Roman expression for two people who are always found together —like my friends Nuccia and Loredana. In case you were wondering, I let them decide between themselves who should be Rocco and who should be the dog. They are good friends that teach in the same school, co-author books, and always seem to be found together.
