Erin really had guts. A first year paying a visit to a professor! But she's doing this ever since, and it always pays her right. In Muggleworld, Erin's quite used to talking to her teachers before classes start. It was her way of giving the teacher an impression about her. It was actually a tricky move. Will the visit earn her points or lose her face in the front of the professor forever? That thought made her stomach churn a bit.

Her hand put together ready to knock at once. She thought twice, put it down and walk away from the door but without thinking, she leaned closer to the door and slowly placed her ear there. Seems like she's trying to hear what's happening inside. She's DECIDED.

KNOCK!
KNOCK!
KNOCK!
