In my own corner, reading.

I wonder about the people who leave bookmarks, but not proper bookmarks, in books. It's a great and subtle mystery, a small treasure to think about. What flight were they on and where were they going? The nature of the journey? Another trip to Corporate or someone running from their past, starting over? Were they tired and this was all the further they made it into this book or did they just sleep and then finish it the next day, never again having to tend the marker?
