I'm Not A Girl Not Yet A Woman (Britney Spears)

 "I'm not a girl
Not yet a woman
All I need is time
A moment that is mine
While I'm in between
I'm not a girl"

The  Changes

Puberty is the time when a child's body starts changing into an adult's body. The average age for girls to start puberty is 10-12 while the average age for boys to start puberty is 12-14.
 Adolescence is a transitional stage of physical and mental human development that occurs between childhood and adulthood. This transition involves biological, social, and psychological changes. 
Adolescent psychology is associated with notable changes in mood sometimes known as mood swings.
The end of adolescence and the beginning of adulthood varies by country as well as by function, as even within a single country there will be different ages at which an individual is considered mature enough to be entrusted with particular tasks, such as driving a vehicle, serving in the armed forces, voting, or marrying. Also, adolescence is usually accompanied by an increased independence allowed by the parents or legal guardians and less supervision, contrary to the preadolescence stage.

The Girl

Annelies Marie "Anne" Frank (12 June 1929 - early March 1945) was a Jewish girl born in Germany.
Anne and her family moved to Amsterdam in 1933 after the Nazis gained power in Germany, and were trapped by the occupation of the Netherlands, which began in 1940. As persecutions against the Jewish population increased, the family went into hiding in July 1942 in hidden rooms in her father Otto Frank's office building. After two years, the group was betrayed and transported to concentration camps. Seven months after her arrest, Anne Frank died of typhus in the Bergen-Belsen concentration camp, within days of the death of her sister, Margot Frank.

The Diary

Anne gained international fame posthumously following the publication of her diary which documents her experiences hiding during the German occupation of the Netherlands in World War II. Her father Otto, the only survivor of the group, returned to Amsterdam after the war to find that her diary had been saved, and his efforts led to its publication in 1947. It was translated from its original Dutch and first published in English in 1952 as The Diary of a Young Girl.
Otto Frank removed certain passages from Anne's original diary, most notably those in which Anne is critical of her parents (especially her mother), and sections that discussed Anne's growing sexuality. Although he restored the true identities of his own family, he retained all of the other pseudonyms Anne had created for the members of the household and the helpers.
The diary, which was given to Anne on her 13th birthday, chronicles her life from 12 June 1942 until 1 August 1944. It has been translated into many languages, has become one of the world's most widely read books, and has been the basis for several plays and films. Anne Frank has been acknowledged for the quality of her writing, and has become one of the most renowned and most discussed victims of the Holocaust.

Diaries: Yesterday and Today

In the past girls used to record their experiences and feelings in secret diaries, which they locked to prevent other people from reading them. Personal diaries were private books which depicted intimate events or expressed inner thoughts. Their entries were supposed to be read only by the writer and not to be shown to anyone else.
Everything changed with the internet. Now people -not only teens- chronicle their lives in electronic format (e.g.  blogs) and expose their lives publicly in a way that would  have been unthinkable in the past.
