There's a big difference between your situation and what is happening w/ kids in their 20s and 30s. Most of these kids live at home b/c they want a maid and not have to worry if the electric is going to be turned off. That's where the scorn is coming from.
I had the opportunity to work with my Dad, too. It was a great learning experience.
There is no difference. I had to go home because I lost a job. It just turned into being something good for both of us when I ended up staying a few years. I don't scorn family for keeping care of family longer than they ~have to~. There is nothing about that decision that should upset anyone.
