I aimed a vicious kick at the bag, managing to get my leg all the way up by my ear. Even the instructor winced when he heard the pounding noise it made.

“Um, Chaos?” He glanced at me. “Is everything alright?”

“Just fine.” I said through gritted teeth, slamming a right hook into the bag and smiling at the sound.

“Positive?” The instructor, Michelangelo, frowned. “Because you’re killing that bag.”

I stopped for a moment, sweat dripping down my face. I was just the teeniest bit annoyed. “Isn’t that the point?”

“Well, I hesitate to say no. Because it is, but what you’re doing is destroying the gym equipment.” Michelangelo looked me over, worriedly.

I spun and put a back kick into the bag so powerfully, that the seam actually split.

Michelangelo’s eyes widened. “OK, that’s it. We’re done today.”

I stared at him incredulous. “Are you kidding?”

Michelangelo ignored me. “And no sparring either, you’ll kill someone.”

“Michelle!” I protested, using my nickname for him.

“Not today.” He was adamant.
