She knew that insults were par for the course with this man, in fact she had heard all of this before even on her best work. It was getting to her this time, though. Her fists clenched in anger as the supervisor badmouthed her work. She wanted so badly to just run him through with her sword, but that would cause too many problems. Instead, she had something far more ironic planned for him. As he was turned away from her, she didn't bother trying to explain why her work was worse than usual after he was done 'criticizing' her work. Instead she stood up and gently placed her hand on his back between the shoulder blades. "Perhaps you need a demonstration of my work then?" She said as magical force gathered in her hand. "After experiencing it first hand, you'll never badmouth me again!" The magic gathered, focused, and was released. Hopefully she had proper control of it under her stress, she needed just the right amount of force, not too strong, but not too weak, and only a concussive force rather than flames so she wouldn't burn the place down.
