How does Ann start her diary? What does she describe in her diary in the beginning?

How does she mature through the course of her diary entries? Elaborate. ( June 14 1942

– July 8 1942) PLEASE. URGENT... THANK YOU...

Anne starts her diary by talking about the point that prompted her to keep a diary. She always missed a best friend to whom she could confide. So, she decides to treat her diary as her best friend. She begins by giving a brief sketch of her life. She matures in the process of writing diary entries. When she gets punished by her teacher repeatedly; she completes even the extra homework with a sense of ingenuity. She is determined to give convincing arguments about necessity of talking.
