You were Hermione Granger's sister. You, Harry Potter, Hermione Granger and Ron Weasley and the other students, were in Professor Trelawney's class, you two were looking at a crystal ball, waiting for Professor Trelawney that was talking to other students.

But you look at Ron and see he was sleeping so you smack the back of his head to wake him up and he gasps and shakes his head.

"Don't sleep in class, you idiot!"

You whisper-yell to Ron and he grin sheepishly and Harry chuckle, the other students didn't notice nor Professor Trelawney.
