Anne Frank decided to create the character of Kitty in her diary to help her deal with loneliness and share her thoughts more openly. By treating her diary like a friend, Anne finds a secure place to express her feelings without worrying about what others might think. This is clear when she writes, “Who else but me is ever going to read these letters? Who else but me can I turn to for comfort?” (Frank). By making her diary a character, she has a special way to vent her frustrations and share her reflections.
Also, Anne uses her relationship with Kitty to understand her problems with her family. She talks about feeling distant from her mother and feeling like no one understands her when she says, “I tell myself time and again to overlook Mother's bad example. I only want to see her good points… but it doesn’t work” (Frank). Plus, her diary gives her a sense of control in a situation where she has very little freedom. Through Kitty, she can tell her own story and explore her thoughts on who she is, what’s right and wrong, and the war around her. In short, Anne turning her diary into Kitty changes it from just a record of what happens into a close friend who gives her comfort and helps her learn about herself during difficult times.
