Some did out of mental health necessity. Some did not and were profoundly lonely and unhappy (my case). And some did indeed ended up having that period to be super happy.

My point is that it is profoundly unsocial way of life for the parent at home. The party even twice a week do not really make up for being completely alone with nothing challenging to do whole day. You can easily end up loosing social skills and those parties end up unfulfilling.

If you go to work and then someone else organizes a party once in a while, it is cool effortless way to keep friends. But, if the stay at home person is extroverted, there is very little social about their lifestyle.
