Shins. And other things that hurt when hit

This mornings drill: 1) getting choked up against a wall (my partner: a 6'2" construction foreman, married, and had a habbit of making sound effects during our sparring), 2) Defending against getting tackled around the legs by flattening yourself on their backs. 3) Blocking getting "smacked around the clock" -- come at them at 12 o'clock, 10 o'clock, etc, all the way until you are going for their groin.

My partner decided that instead of swatting, he would kick at my groin. So I did the same. And he can block pretty hard.
