Why does the reverend mother call Maria into her office in the sound of music?

In "The Sound of Music," the Reverend Mother calls Maria into her office to discuss her struggles with fitting into the convent and her uncertainty about her vocation. She recognizes Maria's spirited nature and believes that she may not be suited for the strict life of a nun. The Reverend Mother ultimately encourages Maria to explore her true calling and suggests that she become a governess for the von Trapp children, which could be a better fit for her personality.
