Dear Mr. Page,
I appreciate you reaching out and letting me know this. I apologize for my patient's outburst, and wish to reassure you that it will no happen again. I believe Dr. Locke mentioned a damaged book, and if you let me know the title, I will personally replace it, as it was my patient that damaged it.
I completely understand this punitive action, and I will make sure that Spike understands it as well.
