Spots in the Sky

It is getting dark earlier now. We were on our way home from a friend's house this evening at 7:30 or so and it was surprisingly dark. Estella, very excitedly, said, "Spots...I see spots!" I was confused. I didn't know what spots she was talking about. I asked, "Where? What spots?" She replied, "Spots in the sky." I realized she was talking about the stars.
