"And the depressed person always took care, when as an adult she attempted to describe to a supportive friend the venomous struggle over the cost of her orthodonture and that struggle's legacy of emotional pain for her, to concede that it may well truly have appeared to each parent to have been, in fact, a matter of "principle," though unfortunately not a "principle" that took into account their daughter's feelings at receiving the emotional message that scoring petty points off each other was more important to her parents than her own maxillofacial health and thus constituted, if considered from a certain perspective, a form of neglect or abandonment or even outright abuse, an abuse clearly connected-here she nearly always inserted that her therapist concurred with this assessment-to the bottomless, chronic adult despair she suffered every day and felt hopelessly trapped in."
That was one sentence. There are many favorable adjectives one could reasonably apply to it, but IMHO "tight" is not one of them.
(BTW, that sentence is not an isolated example. Here's the very next sentence:
"The approximately half-dozen friends whom her therapist-who had earned both a terminal graduate degree and a medical degree-referred to as the depressed person's Support System tended to be either female acquaintances from childhood or else girls she had roomed with at various stages of her school career, nurturing and comparatively undamaged women who now lived in all manner of different cities and whom the depressed person often had not laid eyes on in years and years, and whom she called late in the evening, long-distance, for badly needed sharing and support and just a few well-chosen words to help her get some realistic perspective on the day's despair and get centered and gather together the strength to fight through the emotional agony of the next day, and to whom, when she telephoned, the depressed person always apologized for dragging them down or coming off as boring or self-pitying or repellent or taking them away from their active, vibrant, largely pain-free long-distance lives.")
