When I visit people's homes I love to look at the books on their bookshelves. You can learn a lot about a person by looking at the books on their bookshelves.
This is a picture of a bookshelf that I encountered the other day. I found it a bit ironic. These books look so peaceful as they sit on the shelf next to each other. They are not criticizing or heckling one another. I wish the authors of these books could do the same.
