I would heartily agree that this would be the approach with a typical WAS.
However, I am not sure this is the correct approach to those of us dealing with MLC's?
They are in a state of changing/dealing/coping themselves.
I'm not necessarily saying it's wrong for everyone, but I'm not sure it's right for all those dealing with MLC either. In fact it can change as you go through the journey.
Knowing what to do and when, has all the rules thrown out with the MLC person. It's sometimes a trial and error road, with lots of errors. Even doing what works will change at times. Being consistent is what works for me. Consistently nice. Detaching is a key, but some of those items may have to be looked at on an individual basis. IMO
