Shiny Sidewalks

My daughter Avery, (3 years old), and I were walking outside a museum and she was staring intently on the sidewalk.  She looked at me and said, "This sidewalk is shiny".  I had not noticed and looked down to see there were reflections coming off the rather smooth  grey sidewalk beneath our feet.  As we continued to walk and look at the sidewalk, I said, "The sidewalk is different than other sidewalks, maybe it is because it is made with granite". She nodded in agreement and said, "Yes, like pomegranate".
