“The worst part was that, as the years passed, these memories became, in the way you kept them in a secret box in your head, taking them out every so often to turn them over and over, something like dear possessions. They were the key to your unhappiness. They were the evidence that life wasn’t fair. If you weren’t a lucky child, you didn’t know you weren’t lucky until you got older. And then it was all you ever thought about.”
