Although Anne Frank is living in a most dire situation with her family, her diary reveals that she is still a teenage girl who is expressive, opinionated, and bordering on ostentatious at times. She writes about her fellow family members in hiding and their frivolous behavior given their situation. While writing about her annoyance with such actions, she uses such conduct and previous resentments with family members to justify her own reckless behavior.
Anne Frank's entries also show the typical conflicts experienced among siblings with various personality types. While Margot is attractive, well-liked, and well-behaved, Anne demonstrates a more rebellious attitude that causes tension with her mother. Anne uses this tension to justify her more eccentric behavior, and the fact that her father does not openly disapprove of her gives Anne all the more reason to feel justified in her actions.
However, we also see Anne's humanity, as she can recognize these qualities about herself. In an entry on January 19, 1944, she writes, “Isn't it awful of me to be preoccupied with myself?” Although mostly independent and self-justifying throughout the diary, Anne Frank occasionally demonstrates that she is aware of her own shortcomings.
