Acceptance doesn't mean agree with. In acceptance there is neither agreement or disagreement. Thus you accept fully what is without 'mind interference'. You can thus plainly see the dudes behaviour is not good and enter with appropriate action.
Hi Graham, a couple of questions: what do you mean by "mind intereference"? and regarding your language of "acceptance" are you suggesting that moral judgements of situations i.e. abusive language directed against your wife is wrong?
