Comparation 13/Adrian Mole

There are many similarities between Adrian Mole and 13. In the film the main character, who is Tracy, is thirteen years old, and the main character of the book, who is Adrian, is thirteen too. Another similarity is that both parents of both children are separated, and it's hard for the children.
Next, in both stories, the main characters have a best friend, but at the end of the stories, they seem to be bad friends. Then, there is another similarity, I think it's the biggest similarity of all... Both stories talk about sexual life, alcohol and drugs. Adrian, when he meets Pandora, he gets wetdreams and he does sexual things, he thinks sexual too. And Tracy, starts to drink, practise sex, have boyfriends... things she didn't do before.
I think the film is more striking compared to the book.
