Pia would attend synagogue on her own from the age of nine whilst her parents were working, and by age 14 she was teaching in cheder. As an early teen she began to doubt her faith but continued to practise Jewish traditions. It was in Oxford, when at university, that Pia stopped observing the Jewish faith. Later in life however, she wanted to celebrate her Jewish identity so became involved in liberation seder nights and attended meetings of the Jewish Historical Society.
