I think Sarah pretty much nailed what I was going to say.
For me, the line is drawn when, as a therapist, you make your decisions from the standpoint that you have power over someone's life. I would rather take the view of being there to facilitate a dialogue, a communication, and helping someone to tap into the power they have over their own life.
That involves what Cindy talks about.
To quote Morpheus: "I'm trying to free your mind, Neo. But I can only show you the door. You're the one that has to walk through it."
When someone tells you that you have to walk through it backwards, wearing bright yellow shoes, on the first Tuesday in August, accompanied by two lions and an albino squirrel, because that would make them happy... they've overstepped their bounds.
