How does Breathing Underwater by Alex Flint begin?

The story begins at the Justice Building in Miami, Florida. Nick, the book's protagonist, is up before the court after hitting his girlfriend, Caitlyn. Caitlyn's seeking a restraining order on Nick to keep him away from her. The presiding judge, Judge Lehman, is none too impressed by Nick's arrogance and lack of remorse and has no hesitation in granting Caitlyn's request. Under the terms of the restraining order, Nick is not to contact her in any way, not even talk to her at school. If he does, then he's going straight off to jail.
In addition, the judge also orders Nick to attend anger management classes for six months and to keep a regular journal. In that journal, he's to write 500 words a week explaining all the things that have happened between himself and Caitlyn from the very first day he met her until his court date. The judge hopes that writing the journal will force Nick to confront his unacceptable behavior and perhaps make him learn something.
