At least this kid was able to admit that he/she wasn't the rightful owner of the book.
Good on ya, kid. That's the first step to vandal recovery.
In related news, I wrote Book Riot post a few weeks ago about this very topic: "When Book Graffiti Goes Bad." Check out if you want to see more examples of book vandalism that I've recently found in my library (and most of them weren't already posted on this blog as they are a little darker than what I've posted on here in the past).
Hope you're having a good summer so far, my friends. It's hot outside, but it's nice and cool in the library. Why dontcha go visit yours and see for yourself? (Just try not to write in any of the books, kay, thanks.)
