On my morning commute, I espied a man reading a paperback. I didn't catch the title, but I did notice that the book's covers had been completely torn off. The man would read a page and then fold and crease it under the rest of the book.
It was a interesting method of reading, but my bibliophile heart stopped for a second. I could never imagine treating one of my books that way. I don't even dog-ear my book's pages.
