I guess to put it simply, it’s resilience. That ability to skate through daily life without what society would lead anyone to believe as the essentials for a growing and impressionable small human to positively develop and thrive. In other words, “not fucked up.”
A good 95% of the people I’ve gotten to know over the years with one or a full set of parents, share stories about them that I can never relate. I don’t have such stories to tell. I only listen and wonder if I was lucky for those whose parents were terrible to them or unfortunate that I didn’t feel that familial warmth.
