Although some things Richard does offend me a hell of a lot and I do think he's dense (sorry Richard), I do offer this in his defense. The PR is totally brick-wall blocked about changing her mind and behavior about some things. No matter how often or who explains it to her, she will continue with that behavior or belief. And I do mean that: often and who, no matter. She will get emotional, angry, defiant, etc. I think it's a subtle variation of the perserveration of autism.
