Back to Hogwarts

You took the train back to Hogwarts. Once you arrived at the castle, you walked straight to the Headmaster's office.

Hogwarts' current Headmaster, Phineas Nigellus Black, was waiting in his desk. Seeing you came in, he stood up and greeted you: "Ah, our most brilliant student has returned."

"Sir, I want to ask a favor from you."

"Go ahead."

"I think I found the dream of my life: that's teaching. Can I stay after graduation and become a teacher?"

Phineas touched his chin: "You gave me a hard choice. You're still young."

"Am I unqualified?"

"No, of course not! If you're unqualified, then more than half of our Professors also unqualified."

He sighed and said: "The problem is that our staff is already full. If we have an empty seat... and you're still interested... then I'll call you first."

You could change his decision in one wand movement, but... what the fun was in that? You accepted the challenge since you already had an idea: "Thank you, Sir."

When you're leaving the Headmaster's office, a person bumped into you.
