It was her diary, and hers alone. It was hers to see other people's thoughts, but more importantly, examine her own. Being withdrawn, modest, and shy, she never actually revealed any of these things to other people, unless it was deemed necessary.
The secret she wanted to keep most was one that was just... not intended for other people to see or know about. In fact, she had to admit, her own diary could read her mind better than she herself could.
French kissing? Polygamy? Threesomes? She knew of none of them.
At least, that's what she wanted to say.
