21. The first thing you broke
The first thing Sirius ever broke was an antique vase emblazoned with his family's crest when he was three. His mother was particularly fond of that ugly piece of ceramic for some odd reason and he paid dearly for his misbehaviour.
It only escalated from there. The next thing he broke was his arm when he was seven, followed directly by every piece of china in the cupboard in burst of uncontrollable magic because of the pain. When he was twelve, he broke an entire stone wall within Hogwarts castle. Each time, he paid the price and served the punishment, suffering great grievances.
The last thing he broke was no exception. The only thing different was the fact that it was the only thing he truly wanted to be left whole and he readily admitted his guilt and that he should suffer every pain that came his way and more. Remus' heart would never mend completely, and it was all Sirius' fault.
A/N: The hole in the wall was not originally my idea. All credit for this goes to ObsidianEmbrace in her fic A Life More Ordinary. It is a wonderful story and if you have not read it, I highly recommend doing so.
