Anne's goal is to become a journalist after the war. How do the goals affect her relationship with her mother? With Peter?
I don't see that her goal of becoming a journalist affects either her relationship to Peter or her mother. A journalist is supposed to be objective and impartial. Anne's relationship with these two is any but! Anne has a really common, female, teen-aged, anti-mom relationship going. She seems to think her mother's love is shallow and meaningless. She does not believe that her mom truly cares what she thinks and feels. As a result, she frequently says things that wound her mother. She reports in her diary regularly about how her mother criticizes and makes fun of her. Peter is her first true love interest of a personal nature. She has liked other boys, but never had a deep, meaningful relationship with them, just more of a superficial "I think I like him" one. Peter is the only non-adult available for Anne to confide in as she is not close to her sister Margot very often. Her feelings run from extremely positive to extremely negative, almost of a hormonal nature. She is trying to make Peter something he is not. But, with no one else to try out her developing mature feelings with, Peter becomes her confidante and love interest. Neither of these relationships are of a journalistic nature, though they do provide an opportunity for Anne to report the interactions between the two though in a very biased way.
