And shortly afterwards, that shelf was dust-free just like her desk from earlier. Gotta love the simple cleaning charm that didn't require too much concentration, right? It still got to work even though half of her attention was to her classmates. Her eyes were particularly on her Ravenclaws, making sure they were carrying on the task without so much trouble. So far, so good though.

She had to polish the shelf, you reckon? Of course. Professor Ivy did say to make the classroom spotless and that was exactly was Beezus was trying to do. "Poliotus! Poliotus!" The brunette casted the charm with an S movement and tadaaah! Sparkle. Sparkle. More casting here and there and within a few minutes, the shelf was looking divine.
