Nerida smirked as she came by The Fat Lady's portrait. She wasn't a Gryffindor, she was kinda wondering if she would snap at her. Her brother told her that she had done that to him once...Then again her brother was a bad boy. Nerida gripped her wand and then took hold of the vacuum and then jabbed her wand at the vacuum and said "Vacavus," With a loud vrommm the vacuum came to life. She sucked up the dirt and gunk that was on the floor and in the corners and then slid it up against the wall and against the frame, she didn't want to go against the actual picture due to her being afraid of what the Fat Lady might do..."There you go," she muttered mostly to herself.
