And I don't find your question relevant...
He doesn't have a job and still lives with his parents, so he's still dependent on his parents, so that makes sense.
One real exemple (in rl) :
All my sons and my daughter have always been very independent since very young, and the twins of my husband too. (even if despite everything they are almost always with us in our house, which my husband does not dislike, then we are a very close and united LGBTQAI+ family - of all the seven, only two are totaly straight but friendly) - with my husband we very early founded a blended homoparental family... (we have were previously forced to marry and have children with women when we reached our sixteenth birthday)
(we were still very young when we decided to go to Europe on the other side of the Atlantic to escape the tyranny of our families, of the government, and of justice) - and I think that influenced a lot in the lives of our sons and daughter.
I think that allows you to understand my point of view...?
It's not the age that counts, but the circumstances.
