what's that?

Miles and Shackleton are having a moment sharing Miles' new favorite hobby.  He loves to climb onto the ottoman and watch out the window.  He can climb up all by himself by stepping on the radiator, and pulling himself up by the window ledge.  The only worry of course, is him staying on without falling off.  Shackleton doesn't seem to mind sharing the view.  There is so much for them to see from the window.  Cars, birds, squirrels, airplanes, Christmas lights, and I'm sure the list goes on.  It also gives Miles lots of opportunities to point and say, "hus ha?" which we are taking to mean, "what's that?"  It is also prompting a new favorite word, "car!"
