Rosewood and the Crazy first year

"Hi I am Arabella Rosewood, and I am currently sitting in detention with 5 other people. Now normally I would be at the Gryffindor common room reading, but because of my wonderful friends I was stuck in detention with Autumn, Kristen, Fred, George and Lee Jordan. Now to know how this all happened lets start back at the beginning, right before school." Disclaimer I don't own HP
