Sirius climbed onto the bench next to James and tried to look as ashamed as he managed. "I'm sorry too. From the bottom of my heart." He sighed heavily and let his head hang. "I'm sorry, fellow students. And I'm really, really sorry, Professor Dumbledore, I can't wait to hear your speech. I bet it won't be very boring much."

He smiled, because the headmaster was smiling too. "And I'm sorry I didn't hit him in the face."

Well, he was honest. But he was also still smiling as he sat down next to James again, subtly picking up a piece of crust to put into his mouth. "You are not a teacher's pet." He could admit that, and approve.
