Be careful with this one. She did not say the diary was true. She said it was hers. There is a distinction there. It is hers, and she wrote it. But she didn't say it was true. She can write whatever she wants in her diary.

Think about a young girl or boy as an example who just got punished by their father. Do you think maybe they might write something about wanting to kill their dad? Kids write a lot of emotional stuff in fits of rage or despair.

Now - I think it is true as well, but she left herself an out by not saying that part was true.
