The diary was Anne’s best friend with whom she could share all her secrets. Justify this statement by stating evidence from the text.

In Anne Frank's diary, written while she was in hiding between the dates of June 12, 1942, and August 4, 1944, she clearly states that the diary is her best friend and confidante. In fact, at the very onset of the diary, she writes, "I hope I will be able to confide everything to you, as I have never been able to confide in anyone, and I hope you will be a great source of comfort and support" (June 12, 1942).
Further on in her diary, Anne confides that she really has no friends and that the diary will be her best friend. She personifies the diary, naming her Kitty: "I want the diary to be my friend, and I'm going to call this friend Kitty" (June 20, 1942). In this way, the diary takes on an almost human quality as Anne shares her deepest thoughts and emotions with her friend, 'Kitty.'
Throughout the years that Anne wrote in her diary from the ages of thirteen to fifteen, she depended on the diary to "listen" to her. She wrote about her fears, her hopes, and her life in hiding. She wrote about becoming a woman: "It's such a momentous event" (Nov. 2, 1942). All that a young girl would share with her friends, Anne shared with Kitty.
Toward the end of the diary Anne confides to Kitty that she has two sides to her personality: "I'm split in two. One side contains my exuberant cheerfulness, my flippancy, my joy in life . . . [the other side] is much purer, deeper and finer" (Aug. 1, 1944). Anne goes on to state that other people have not seen her 'better' side. In this way, Anne's diary, Kitty, has become her best friend, the only friend who has seen the real Anne.
