Is your TKD instructor really strict? I know that mine is and I respect her for being that way. Outside of class she is a really nice person. But once class starts she is all business. For example if you test for a TKD belt, and testing is usually 4+ hours long, and you throw up from the hard work, you are done. Or if you cry during the test, you fail. I am not sure if this is how other instructors do it, but I would be interested in hearing if other instructors are that strict. I see nothing wrong with this, and did not know if it was a universal thing or not.
