At the age of 13, her father gave her what was originally a journal for her birthday but she used as a diary. The diary was red, white checkered cloth with a small lock in the front. She wrote in it to maintain her sanity and spirits.The tree outside the window where they hide in the concealed room inspired her all the time to write in the journal. Her first entry said .. "i hope i will be able to confide everything to you,as i never been able to confide in anyone,and i hope you will be a great source of comfort and support." The first thing she wrote about was about her imaginary friend named "kitty." She became famous because she was a young teen with a big talent but she didn't live to enjoy it.
