“I get frightened myself when I think of close friends who are now at the mercy of the cruellest monsters ever to stalk the earth.”

“I feel wicked sleeping in a warm bed, while my dearest friends have been knocked down or have fallen into a gutter somewhere out in the cold night. I get frightened when I think of close friends who have now been delivered into the hands of the cruelest brutes that walk the earth. And all because they are Jews!”

“No matter what I'm doing, I cant help thinking about those who are gone. I catch myself laughing and remember that it's a disgrace to be so cheerful... This gloom will pass.”

“I finally realized that I must do my schoolwork to keep from being ignorant, to get on in life, to become a journalist, because that’s what I want! I know I can write ..., but it remains to be seen whether I really have talent ... And if I don’t have the talent to write books or newspaper articles, I can always write for myself. But I want to achieve more than that. I can’t imagine living like Mother, Mrs. van Daan and all the women who go about their work and are then forgotten. I need to have something besides a husband and children to devote myself to! ... I want to be useful or bring enjoyment to all people, even those I’ve never met. I want to go on living even after my death! And that’s why I’m so grateful to God for having given me this gift, which I can use to develop myself and to express all that’s inside me! When I write I can shake off all my cares. My sorrow disappears, my spirits are revived! But, and that’s a big question, will I ever be able to write something great, will I ever become a journalist or a writer?”

“If I talk, everyone thinks I'm showing off; when I'm silent they think I'm ridiculous, rude if I answer, sly if I get a good idea, lazy if I'm tired, selfish if I eat a mouthful more than I should, stupid, cowardly, crafty, etc., etc.”

“Ever since I was a little girl and could barely talk, the word 'why' has lived and grown along with me. It's a well-known fact that children ask questions about anything and everything, since almost everything is new to them. That is especially true of me, and not just as a child. Even when I was older, I couldn't stop asking questions. I have to admit that it can be annoying sometimes, but I comfort myself with the thought that "You won't know until you ask," though by now I've asked so much that they ought to have made me a professor. When I got older, I noticed that not all questions can be asked and that many whys can never be answered. As a result, I tried to work things out for myself by mulling over my own questions. And I came to the important discovery that questions which you either can't or shouldn't ask in public, or questions which you can't put into words, can easily be solved in your own head. So the word 'why' not only taught me to ask, but also to think. And thinking has never hurt anyone. On the contrary, it does us all a world of good.”

“But it's the same with all my friends, just fun and joking, nothing more. I can never bring myself to talk of anything outside the common round.”
