Hey Hey It's Esther Blueburger (2008)

A coming-of-age comedy that explores what it's really like to be an outsider in your own world. Esther is not like other girls; she befriends a duck, talks to God through the toilet and break-dances at her Bat Mitzvah. Her all-girls private school is a daily torment of mind-numbing conformity and bell-ringing rituals. Home is a pressure cooker driven by her mother Grace's demand for perfection. But life changes when Esther meets Sunni and her mother Mary. She learns that it's OK to be different and being true to yourself is more important than fitting in.
