The Thinker

Three or four times each day, we read the book "Goodnight San Francisco" together. It's one of your favorites, yet some pages consistently do not hold your interest. One of these less engaging pages highlights Rodin's statue, The Thinker. One of the original casts of this famous treasure stands in the courtyard at the Palace of the Legion of Honor museum.
While at the museum yesterday, you took a long, hard look at The Thinker. Then, this morning, I noticed, for the first time, that The Thinker page in your book held your attention for the first time. I was looking for a hint of recognition in your eyes. You're making many more associations these days so this seemed to be the explanation for your new found interest in this portion of your book. Now, can you answer the question the book poses: "Good evening, statue of The Thinker. What are you thinking about?"
