We all know (I hope) that if your spouse tells you, "Honey, I think I broke a bone; will you please drive me to the emergency room?" that The Right Thing to do is get the car keys and not argue - am I right?
Yes, you're right.
But you're right in a language the OCPDr, at least in my experience, doesn't grasp in practice. Intellectually, in theory, in fantasy, sure. But in taking action? That alien, otherness that I often speak of - this is the heart of it.
What happens in these situations is a system breakdown, "file not found," from what I can tell. The rest - any action the OCPD'r does actually take - is fallout, dysfunctional, nonfunctional, whatever. Shame, frustation, fear, become defensiveness, anger, blame.
Empathy & compassion flow on impulse, a word more often associated with things like fun and spontaneity. But when you think about situations calling for empathy, some being illnesses, accidents, emergencies, these are unmapped territories that a person acts on with impulse, to caretake, to help, to allow the other to heal and feel better, without concern for doing it right. I'm not talking morally here, I'm talking protocol, even where and when protocol simply doesn't apply. We impose the word moral here sometimes in regard to the OCPDr but as I have before, I disagree with that. OCPD'rs work with plans and maps and protocol, those sorts of sanctioned "right" ways. But no two situations like these are alike, even if an illness repeats, or some detail may be similar, there are so many x factors that each one is completely unknown and uncharted. There's literally no conduit for the empathy to flow from.
Now, if a situation does repeat closely enough, or I've observed someone else taking the exact same action that's called for - I may do fine. If my brain detects a match, inside what happens is "aha, I know this one. I can do this one." Break a second bone a week later and I'll drive you to the ER without hesitation, so long as there's a clean & clear view of action to be taken.
