here's the scenario: late sunday afternoon, three higher level students, with a better grasp of english. lesson topic: stress management; i printed out meditation exercises, one on breathing, one on muscle relaxation. when we got to the muscle relaxation exercise, one of the instructions was "clench your butt, relax. Do three times."
so first of all - chinese have no butts, or very few that are worth mentioning
second, we're talking of a part of the body they try to avoid thinking about
third - they're like teenage boys when it comes to anatomical parts like the butt. You say butt, they laugh nervously
so I try to explain, they titter, and struggle to do the exercise
i try to say they can do this while standing in line, good for the posture, core yada yada
one girl says to me "but it will look strange!"
I tell her and try to show them that (pointing to my ass) "see? can you see if my butt is clenched? Nope!"
i'm standing sideways mind you, and one relatively buff guy is sitting in front, his eyes now forced to look at his english teacher explain that her butt is clenching, relaxing, clenching, relaxing
