I'm in my late sixties....and the height of the baby boomers was in my time.
We couldn't wait to get out of our parents' homes......but we still very much loved our parents. Christmas....birthdays...anniversaries...weddings and funerals always were family matters. 
However......if we wanted to entertain other friends ..or lovers....we knew we couldn't live in our parents' homes. If we wanted to smoke or drink ....we couldn't expect to do that in our parents' homes.
Nature ...and reality...demanded that we leave the nest.

Nuff said
