(i) Anne needs to give a brief sketch about her family because she feels that no one would understand a word of her stories to Kitty if she were to plunge right in without any background information. Even though she personally dislikes providing this outline of her life, she recognizes that it is necessary. Without it, her diary entries would lack clarity and meaning for the reader.

(ii) Anne treats 'Kitty' as an insider rather than an outsider. She explicitly mentions that she wants the diary to be her friend and that she can confide in it more than in people. By sharing intimate details about her life—such as her adoration for her father, her emotional farewell to Mrs Kuperus, and her deep love for her grandmother—she treats 'Kitty' as a trusted companion. Providing a background sketch is her way of letting 'Kitty' into her life completely, ensuring her friend understands her past and present. This level of intimacy and trust proves that 'Kitty' is a true insider to her thoughts.
