"Fancy seeing you here, Professor McGonagall." He turned to smile at the tabby, but it had gone. Instead he was smiling at a rather severe looking woman who was wearing square glasses exactly the shape of the markings the cat had had around its eyes. She, too, was wearing a cloak, an emerald one. Her black hair was drawn into a tight bun. She looked distinctly ruffled. "How did you know it was me?" she asked.

What’s your favorite McGonagall quote or moment? Mine is how she never forgets to turn on the light in the darkest times, like raising her wand after Dumbledore’s death and her humor during the Battle of Hogwarts.
