There are rules to sparring, whether it's Muay Thai or Boxing or whatever
One of them is (only absolute idiots need to read this), not to kick 40kg girls with a power teep if your weight is 120KG.
The bright side of this is I got a green light from the coach to knock the guy who did it with a full-power liver kick, so I did.
Oh boy, that felt good. I'm good and evil at the same time, I guess. I will do it to him again, also, hihi.
