Please don't confuse THIS^^^^^ and detachment. Your responses to her various attempts (tests!!) show me a detached/let go mindset. You have also removed the OUTCOME from your thinking. That is all good. You may NOT be done standing for your M.

Exchanges never are perfect. Some are just better than others. Think you did well. Her actions and your responses may have got you back to before the "whatever" comment.
