There is tremendous pressure in the US culture (that I have come across to date) for middle to upper middle class (and even wealthy folks), no matter their circumstances, to consider their lives to be very busy and stressful.
NO MATTER ONE IOTA THE OBJECTIVE FACTS.
And if their lives are in some way NOT stressful, people have this unbelievable need to make things MORE stressful for themselves.
Working folks, Stay and home parents and retirees alike.
Yes, including you. and me.
All I can say is that for me, understanding this cultural drive people have to pretend stress and overwork makes it a TINY bit more understandable.
Perplexing in the specific case perhaps, but vaguely understandable in the general.
