Yup.

The way April describes it, she and her older sister had a warm, playful relationship with its healthy give and take just as the Irving Berlin song describes. But then came school. Her sister was almost three years older. The elementary school put a three-year chasm between them as absolute as the one between Lazarus and the Rich Man in the afterlife. The lower and upper grades rarely mixed, and when they did, her sister treated April exactly the way she treated every other person in her grade: she ignored her. What had happened? School had happened.
