Anne Frank: The Diary of a Young Girl reveals Anne Frank's most personal thoughts during the time she and her family are in the Secret Annex for their own safety, during the occupation of Holland between 1942 and 1944. As Jews, her family rely on the goodness of a few people who keep their secret and help make their living conditions bearable (even if only marginally). Anne's diary which she affectionately names "Kitty" is a means for Anne to deal with some of the frustrations of life in the Annex and also to help her come to terms with the complex relationships she has, particularly her relationship with her mother.
In Anne's diary entry dated Sunday, January 2, 1944, Anne reveals that she has been looking back over her diary and realizes how many times she has written about "Mother." Even though she is the one who has written everything that she is now reading, she is shocked at the intensity of her apparent hatred for her mother, and with the dawn of a new year, Anne is taking a more mature approach and using this opportunity to reflect on her own shortcomings and previous lack of perspective, especially her mother's perspective. Anne confirms that "the period of tearfully passing judgment on mother is over."
