My first yoga teacher was this fiery South African woman, and she'd call you out by name! "FRANK! NO!.." "WHAT ARE YOU DOING?"... Of course she was just being playful and joyful but to your point, she'd run up right on you, grab you, jerk your body into into position, push your back straight, whatever... Kind of old school, but she was super pc/liberal in other ways... Great post lol ;)
