I am so surprised, given Stephanie’s chequered history, and choice of partners, that her children have turned out so well! They all seem very nice, and seem to achieve a sense of normalcy and purpose in life.
I think that Stephanie, like some people, can only do one thing and that thing is being a parent.
Better to be a master in one thing especially if that thing is parenthood, than an amateur in a plethora of things.
