This. It wasn't your fault so why the hell should you pay for it? Who cares who's (whose?) fault it was? He did it, he should be responsible and pay for it. Saying "it was an accident" should NOT be an excuse. Going with that logic, North Korea could nuke America then say "well, we didn't mean to, there was a technical error that set the bombs off, so it's not really our fault so you guys should just forgive us." Sounds pretty ridiculous doesn't it? And who knows, even if he does explain the situation, he might not have to pay for it. The librarians might be nice and let it slide since it's only a title page.
