The point I take away from it is the following question, "Who's doing the framing here?" If you're supporting the other person in framing things themselves, then it leans toward clean language. If you're interjecting your own framing, then it leans away from clean language. Personally, I struggle the most with trying to avoid labeling something as "good" or "bad" for the other person. They're full human beings with their own ability to decide how they feel about something and the best way, in my experience, to decide how you feel about something is to put it into words and notice the feelings that come up as the words are said.
If someone is interjecting their own takes, it gets in the way of that noticing.
I'm really curious what you think about manipulation when you envision yourself listening this way.
