I've heard therapists in a hospital setting say this to others.

Ok, this is a bit snarky, but I've never trusted the phrase.
To me, it always sounds like one of the following:

* T: I need a politically correct way of saying "I don't understand you"
* T: I need a politically correct way of saying I think you are too impaired to hear me
* T: I'm expecting your way of seeing the world and mine to be the same, and despite my years of training I am still shocked that we see things so differently

Not a fan of the phrase.
