I don't quite understand this statement. Our kid lived at home, attended college and grad school, and worked a part time job.
He was not a child, but a man, in our eyes.
He lived at home because he was wise enough not to go into debt in order to live on campus (he paid no tuition for his two degrees thanks to merit scholarships and teaching assistant position in grad school.) He "launched" (got his own place) when he had his degrees and a full time job (he was 21.)
The discipline he showed to deal with work and school was amazing, just because he lived at home while doing it didn't make him a child.
I didn’t clarify my statement when I first posted it. Nothing is wrong with living at home while working toward a degree. It’s smart and very conservative. That’s not what the linked article is about, though, and that is what I was responding to in my initial posts.
