Anne Frank

Anne is a mature girl in a sense that she does not complain of losing her freedom in the situation she is in. She knows that if she complains or grumbles, her family members might feel worried for her.
Though Anne may feel bored and unhappy at the same time, she still has to endure the pain she is going through. She may think that what does life worth now since she cannot have her freedom. Anne is also a typical teenager who enjoys having her freedom. So, she may not be that comfortable with the kind of life she is having now. She wants to be with her friends.
Anne, now, has to live with people whom she does not like- the Van Daans. But, she understands that she cannot make a big fuss about that as she knows they have to live in harmony. They are now in the same boat, which is to hide from the Germans, so she has to put up with them, no matter how unhappy she is.
Anne is a girl who is quite vain too. She actually tells her dairy that many guys in her class tries to get a glimpse of her. She is very frank in her dairy.
Now that they are in the Secret Annexe, Anne has to pretend that she is fine with the way they are living. She cannot show her actual expression and feelings.
Anne is really a sensible girl, whom most teenagers should be.
