I went to a thrift shop recently, nothing of interest except for a book that's an old favorite of mine but in the language I am trying to learn. It is more difficult than picture books to read, but I am suprised how much I understand just from remembering how the story goes. Since I thrifted it I get the sense that I don't really need to be careful with the pages so I fold the corner as a bookmark. I wonder if this is unkind to the book as its not its fault that it is beat up. If it were shiny and new I would treat the pages more delicately. Cruel?
