"Professor Dumbledore?" Miss McGonagall inquired as she stepped into his classroom, her robes swaying softly against her stiff posture. Dumbledore stopped explaining how to transfigure a button into a gumdrop to his first years and looked at her.
"Yes, Miss McGonagall?"
"The Headmaster wishes to see you in his office, sir."
"This cannot wait?"
"Apparently not sir, if he decided to interrupt your teaching." Her wit sharply stabbed his momentary stupidity. The class fell completely silent not expecting a 7th year to reply so caustically to a teacher. But Dumbledore truly appreciated her for being so blunt with him. He chuckled.
"Well then. You'll just have to teach my class while I am gone." He told her eyes sparkling matching his outrageous robes.
"Sir?"
"I was just teaching them to transfigure a button into a tasty gumdrop and since you are my number one transfiguration student who just happened to be sent by the Headmaster to fetch me I shouldn't let such talent go to waste."
With a conspirator wink he left the room quickly after seeing Miss McGonagall's lips curve upwards. During his walk through the various secret passageways he pondered what Dippet wanted. He was not usually ever interrupted by anyone unless it was important. He was grateful that Miss McGonagall with her no nonsense attitude and brilliant academic skills would handle his first years. He had complete confidence in his top student and knew he made the right choice assisting her to become an animagus. With complete confidence in her skills he opened the door to the Headmasters office and went inside.
