"living with you parents is childhood"
For me, I still with with my parents at the age of 24, and although they do try to let me be independent, I still get treated like a child some times, and they still seem to think they have a right of control etc which a parent uses.
So for me, yes this statement sounds true.
I do however, like the closeness I have with them aswell.
If it was up to me, and I had enough money, I would buy at an estate and move my family to the estae, so they all have their own homes and independent lives, but still be close. (obviously i wouldnt force them to live there if they didnt want to).
I wouldnt mind living next door to my parents.
