What I'v learned about the book or w w 2

I learned a lot about the book and I learned new stuff about world war 2 since we have been reading Anne Frank's diary. I already knew stuff about the story and I knew stuff about World War 2, from back in middle school. I didn't know that Anne and her family lived in Amsterdam. I'm going to go to Amsterdam someday before I pass away, hopefully there aren't Nazis around.
