But this... This sound wasn't sad. Why... this sound sounded glad. Every who down in Who-Ville, the tall and the small, was singing... without any presents at all! He hadn't stopped Christmas from coming. It came! Somehow or other... it came just the same.
The Narrator describes that the Who-Villers were singing, and sounding glad. He explained that despite presents Christmas had come anyway. We see the Grinch listening and then it pans to the Who-Villers in a circle singing.
