Harrison was playing today, when I looked over and saw that Marley was supervising his playing. I am pretty confident that Marley isn't capable of thinking complex thoughts, so I am sure this was by mistake. In fact, I am sure that the only thoughts that go through Marley's head are "Ball, Ball, Ball," "I'm a Dog," and "Treat." Either way, I thought it was very cute that she put her head down next to Harrison's. Whether Marley can intentionally think about Harrison or not, I do think that they will be best friends in the near future.
