Fitness Kickboxing...to the death!

Most of the time in Fitness Kickboxing and JKD 1, I'm one of the more advanced students when it comes to basic boxing. I spend a lot of time working on THEIR form and their feeding technique. But not last night.

There is a girl--she has twins, is "girl" a wee bit condescending??--who comes to the dojo in spurts. She happens to have great legs, a friendly disposition, and a black belt in Muy Thai. Her smile is arresting. Big and honest, she has one tooth in the front row that juts at a precarious angle. Is it a simple renegade tooth making trouble for her brothers and sisters or the result of something vicious, a punch she had for breakfast early in her training or an oopsie, a clutsy mistake we all make, like walking into a pole or it could be the scar of her own personal trauma. The smart money is on the knuckle sandwich.
She-- Oh that's right, she's not JUST a black belt, she passed an instructor level examination. Regardless, I haven't worked with her in at least nine months. When it comes to feeding, it's pretty easy to sit on your heels, get a little too comfortable with beginners. Not with her, I was fighting for my life. She wasn't out to kill me, she's just that good. She has speed, she has intent, and she seemed to lean forward a little.
I couldn't tell if that's what she was doing or the way she carried her head, I was too preoccupied with not getting hit! In fact, during one of the two other times I've fed for her she whacked me twice, once in the eye, once in the mouth. This made me feel tentative. I grabbed my mouth guard at the first opportunity.
"Mouth-guard? You don't trust me?"
"No." And no disrespect was intended, just the opposite. Her punches are straight, and if you ain't ready you will get popped. Despite being a little scared--scared of a girl yes, I admit it--I want to work with her again. She pushed me from both directions, and offered the occasional constructive criticism.
"When you bob and weave, look at my chest." Now there's something you won't hear a woman say very often. I kept this observation to myself.
