Let's try to unpack it. .................................
In fact both those expressions, and most of the rest quoted can make perfect sense, and be helpful at times.
What I dislike is when this sort of language is used as a way of avoiding some tricky issue, by manipulating the discussion so as to slip round it, but at the same time giving the illusion to the other person or people that it has been dealt with, or indeed that there is no problem. That's to me what the term psychobabble means - not so much the words and the phrases, but the way they are used.
"Quality time" should mean, for example, that, alongside the normal time when a parent is there and available to a child, there will be some times when they make a special effort, and sort out differences, maybe. But it typically gets used in a way that implies that what's best for children is measured doses of intense parental attention alternating most of the time with absence. Whereas most of the time, it seems to me, what kids need is a parent somewhere around, available if need be, but not dominating things. Non-quality time, in fact.
Rationing time can indeed be inevitable sometimes, and trying to make the most of what there is a sensible way to try to compensate - but the term is used to suggest that it's really just what is needed, and to suggest that without actually examining it.
"I hear what you say" should mean "This isn't the time when I can talk about what you have just said - I may agree with you or I may not agree with you. There is something else we need to talk about right now". And it's a very economical way of saying that. But it often gets used is to say in effect "I can't be bothered to reply to what you say. Now you listen to what I am going to say." But using the expression makes it harder for the recipient to object.
