While Anne's diary itself survived the fire that destroyed the Secret Annex, her favorite possession was a small, red leather-bound notebook which she used to record her thoughts and dreams. It was destroyed in the fire, and Anne was heartbroken. She writes about it in her diary, expressing how much the notebook meant to her.
It's important to remember that Anne's diary was not her only valuable possession. She was also deeply attached to her friends, family, and the hope for a future she longed for. The fire, and the tragic events that followed, took much more than just her notebook.
