At the start of Anne Frank's diary, she comes across as somewhat vain. This is seen in her entry dated Saturday, 20 June 1942, in which she refers to boys who "become enamored on the spot." This entry also refers to the fact that when she goes for ice cream, there is always a young man willing to pay for it.
Later, once Anne and her family have moved into the annex, we discover a young girl who is a typical teenager in her dislike of her mother and her hormonal sensitivity. On 30 January 1943, she describes herself "seething with rage" after an argument with her mother and expresses a desire to scream at everybody who lives in the annex.
Over and above being a typical teenage girl, however, Anne displays remarkable courage and tenacity, despite the immensely difficult situation that she and her family find themselves in. She expresses this, along with the realization of her own mortality, on 4 April 1944, with the words "I want to go on living, even after my death!"
