Remember the first time you went away from home for an extended period of time? Your mother made sure you packed warm socks and clean pants, even if it was going to be 40 degrees Celsius in your final destination. She called and wrote you often, making sure you were eating your vegetables and brushing your teeth. She loved and worried about you. I imagine this is what the Musée d’Orsay is going through at the moment, having sent one of its most precious babies off to Italy for the summer.
