my N parents didn't teach me basic life skills either, but this is one where I kind of let them off the hook a little. they didn't have a lot of life skills to teach. they're hoarders, they have money problems, they have hygiene problems, and more. they're barely holding it together.

your mileage may vary of course. I have a friend whose dad is an incredibly high-functioning narcissist, and if my parents had been that, I would be mad if they hadn't taught me the high-functioning part.

the only exception is that when I was growing up, my dad made his living off an incredibly practical skill that he was good at. he had his own business. he never taught me this business, not even enough to handle my own problems in this area. (he did a type of practical work which literally everybody needs done at one point or another, where you can save a ton of money over the years if you know how to do it yourself.)

I was the SG, but he never taught it to my GC brother either. he could have easily had us both work in his business and learned the basics of this skill. he was just so self-absorbed that it never occurred to him to think about our futures at all.
