I rather like the idea of being an author and then being mistaken for a vandal by signing copies of my own book. This happened to famous author Stephen King on a trip to Australia. Apparently he was wandering around a bookshop and decided to sign several copies of his own books. Bookshop staff immediately ran over in the belief that he was vandalising the books.
The BBC reports: “Bookshop manager Bev Ellis said: “When you see someone writing in one of your books you get a bit toey [nervous].”
