How did the interpersonal conflict between Anna and Elsa in Frozen happen?

In Frozen, the conflict between Anna and Elsa happened between Anna and Elsa's mother, Lily, Anna's grandmother. Lily was a very traditional witch. She firmly believed that magic must obey moral norms, so she imposed strict restrictions on Anna and her family. These restrictions led to a conflict between Anna and Elsa because they thought Lily's actions were wrong and Lily thought her actions were necessary. In the movie, Lily punished Anna and her family with magic, including forbidding them from entering their ancestors 'graves and contacting their ancestors. These restrictions were very painful for Anna and Elsa. They thought that these restrictions were punishment for their parents. So when Anna and Elsa found out that they could visit their ancestors 'graves, they tried to stop Lily from enforcing these restrictions. Lily finally realized that she was wrong and apologized to Anna and Elsa. This interpersonal conflict was also one of the important factors that led to the deterioration of Anna and Elsa's relationship. In the end, Anna and Elsa decided to leave Lily for a more free and independent lifestyle.
