" All these cousins can start a sentence in one language and finish it in another. They need these languages as the family travels to Odessa, to St. Petersburg, to Berlin and Frankfort and Paris. They also need these languages as they are denominators of class. With languages, you can move from one social situation to another. With languages, you are at home everywhere. "

― Edmund de Waal , The Hare With Amber Eyes: A Family's Century of Art and Loss
