The House Elf let out a laugh when the witch said he was being mean; Woopy was over one hundred and this human looked to be a first year. This wasn't him being mean - this was just him being himself. Maybe that was mean. Woopy had no idea.

"Perhaps you shouldn't either!" Woopy exclaimed and climbed onto a nearby table to square up to her. She reminded him of Slytherin; she was just as rude and self-entitled as they were; yet her robe colours suggested she was in that other house with the lion.

He knew he couldn't really do anything as he was bound to serve those within the halls of Hogwarts - though that wasn't to say he couldn't have fun. And fun he was going to have.

After all, it was his job to clean and this girl - this rude, impolite girl - was most definitely making a mess.

Woopy nodded toward her with a profound blink and her hands began to disappear as an invisibility spell took hold until all that was left was her clothing hovering in the air.

The House Elf started chuckling and jumping on the spot, "Being invisible is fun! Ha! Silly witch is now invisible and won't stare anymore."

Of course, the spell wouldn't last long and to Woopy out of sight meant out of mind.
