"Professor, I'm sorry. I shouldn't have looked. I'm sorry," Neville said nervously.
"It is quite alright Neville. Curiosity is a burden to us all." Dumbledore walked up behind Neville and placed a hand on his shoulder.
"What is this?" Neville asked.
"This is the Mirror of Erised, a very peculiar artifact that I uncovered in the Middle East during my youth."
"What does it do?"
"Have you not figured that out Neville?" Dumbledore's words forced Neville's eyes away from the image on the glass.
"It…it shows what I want," Neville said softly, almost as if he was talking to himself.
"Yes, the mirror has unique enchantments that show the user what they want most in the world. It is a great tool for self-discovery but it can also be a siren for those that do not guard against its power." Dumbledore reached out and pulled the curtain back over the mirror.
Neville nodded. "I can see that. If I could sit around and see my family all day I don't know if I would want to move," he whispered, the statement sounding as if it were a secret.
He turned back to Dumbledore and asked, "What do you see, Professor?"
Dumbledore looked Neville in the eye and said, "Forgiveness," before walking back to his desk.
