I have memories as a kid of being so obsessed with the Geronimo Stilton series that i stole countless books from my elementary public school to the point where i filled the bookshelf in my garage. The school allowed students to check out a certain amount of books a week but i burned through the books so i had to resort to stealing to feed my addiction. I was never caught and i never returned the books.
