I think Barbara did great. When I was young I used to have mixed feelings about my parents giving me space and not intervening in my life, which was at a complete stop. They had no escape, I considered them idiots for trying to intervene, but also idiots for NOT intervening on it.. how could they just watch me fail at life everyday? and stand on the sidelines?
I had to set an appointment for myself with a psychologist after internet addiction was destroying whatever piece of career i had left. I would have been angry at them for invading my life, but also love them for trying, and in the end, i think i would have valued the effort to 'fix' me more than anything (just not as it was happening).
What Barbara did was right on target, a seemingly little caring and sincere push, inquiry, or however you want to call it, was really an act of love, and thats what some of us miss the most.
There were times when I would think 'why dont they kick me out? i really hope they do, maybe i would learn to live on my own then'. I dont think that would have gone well tho.
