Frowned upon? How so? What a pity! At least the professor had given her a thin smile in response to her hopeful grin. She would take it as a small sample that he couldn't be that stone-person-without-feelings she had supposed him to be.
He asked about dead people... she knows lot of people who had died. At Hogwarts? She didn't know much about Hogwarts's History.... But, yeah! A idea popped in her mind and quickly she raised her hand and waved:
"Professor! The Fat Friar! The ghost of my house! It seemed that he was one of the firsts students of Hogwarts! Oh!" She covered her mouth with her hands:
"I don't know when he died and I'm not sure if he died at Hogwarts, but... He knows everything about Hogwarts or much more about History of Magic, I guess" , she had a gleam in her eyes as she said it.
