Understood, but the article and my point are, this tread is now growing rapidly.
I grew up in a three generation home. Times were different then. The Grand pa was retired. Grand ma never worked. Both my parents worked and my sibling and I stayed home till out of college.
I am facing a three generation home now...oldest one retired, wife working, her daughter quit job, has no education, left drug dealing boyfirend and now is pregnant with nowhere to go but guess where.
Then again, it may be two households, one with a single older gentleman living alone.
