K raised an eyebrow slightly as Schmoe clearly forgot her name, but considering memory loss and the amount of students he had anyways, she wasn't too upset by it. Honestly, she didn't know half of the names of the people in the class either, so the fact the Professor's usually remembered everyone was quite impressive. She decided not to help him out and offer it, as honestly it would probably be forgotten again by the end of class because HOGWARTS.

Oh good! Moving on to the next move! But... Er... They were jumping to switch legs? Well, she certainly loathed the idea of all the splashes and considering how many people seemed to be falling already she was quite concerned by this move, but who was she to question authority? This class.

She started doing her weird leg switch jumps -- not at all sure what these were called -- when Professor Schmoe threw a beach ball into the fray with some instructions on how to proceed. She caught the ball, pausing momentarily in her exercise, and looked down to see her right thumb on white. Err, singing?!

She sighed softly, and considering she couldn't REMEMBER her favorite song, she jumped into another kid's tune which was the first thing to pop into her head. "Iiiif you're happy and you know it, clap your hands."

Good enough, right? She threw the ball on to the next person.
