Why do the nurses call ally miss Hamilton instead of Mrs Calhoun in the movie the notebook?

In "The Notebook," the nurses refer to Allie as "Miss Hamilton" because that is her maiden name. Throughout the movie, Allie's past and her relationship with Noah are central themes, and using her maiden name highlights her identity before her marriage to Lon Calhoun. It reflects her deep emotional connection to her past and serves as a reminder of her true self, which is intricately tied to Noah.
