Far in the future, Hannah will have a boyfriend named Mike with whom she'll talk about her father. She'll say she isn't sorry about her upbringing before the divorce, that she thinks in a lot of ways it was useful. Being raised in an unstable household makes you understand that the world doesn't exist to accommodate you, which, in Hannah's observation, is something a lot of people struggle to understand well into adulthood. It makes you realize how quickly a situation can shift, how danger really is everywhere. But crises, when they occur, do not catch you off guard; you have never believed you live under the shelter of some essential benevolence. And an unstable childhood makes you appreciate calmness and not crave excitement. To spend a Saturday afternoon mopping your kitchen floor while listening to an opera on the radio, and to go that night to an Indian restaurant with a friend and be home by nine o' clock--these are enough. They are gifts.
