Anne was a popular and outgoing girl before the family went into hiding. Her behavior in the secret annex reflects her natural tendency to be inquisitive. Her questions sometimes drive Mr. van Daan and Mr. Dussel to distraction and they yell at her to be quiet. Mr. Frank provides Anne a diary so she will have an outlet for her thoughts.
Anne is a typical rebellious teenager and is rude to her mother; she attempts to secure her father's support of her desire to defy her mother's restrictions. She is jealous of her sister's intelligence although she does love Margot very much. At one point, exasperated, she vents her frustration about being compared to "Margot, Margot, Margot!"
Anne is kind and generous; these qualities are demonstrated when she presents Hannukah gifts to all her fellow inhabitants of the secret annex.
