Twilight entered the classroom and had to admire the work of her professor. She wasn't creep ed out by the dimmed room after all grandfather's residence had alot of places with no electric so this was normal.
She read the note and then looked around. She noticed the Grey Lady and started over to her second favorite ghost in the house, when she heard Peeves cackle and heard the swoosh of water balloons.
She quietly took out her wand and used a shield charm to avoid getting wet. Actually she liked Peeves in spite of himself and smiled to herself in secret. Finally she arrived at the desk next to the Grey Lady;

"Can i sit on the other side of you my sweet Lady?" she asked.
