Yep! My folks literally went into panic mode, when my sister and I got close to people outside the family (my brother could do as he pleased-- until he got engaged). Dad would stand in the doorway and scream at friends who brought us home, or came home with us. My folks constantly tried to chase off our friends. They opined anyone outside the family was,"up to no good." They also told us, "What happens in the family stays in the family."
Pretty creepy and secretive, huh?
No big secrets, either. Other than that Dad was a high-functioning alcoholic, and was boinking his secretaries.
But, in such families, independence in any member is seen as a threat. So, they act as if there is a mutant brother in the basement, with tentacles. There is also the double threat that the independent member OR outsiders might find out that the family isn't perfect (dysfunctional families also have crazily high family image standards). So, the insular family often tries to quash outside relationships.
Example: Seen the Anthony's social friends, anybody? Neighborhood barbeques? Rotary Club? How about CA trying to break KC's engagement to JG?
So, we stopped bringing friends home. I disappeared into another town, when I was old enough. My sister married to get out to the house. My sister-in-law just toughed it out, until the attempts to chase her off finally stopped (when she had kids).
By the time my sister and i got back in touch, the folks had backed off of any attempt to control.
It took my sister and I a long time to get past being hit, now and then (back then, hitting was considered good parenting). And, getting over the messages that we were unattractive and unloveable. I thought I was very homely for a long time. I later became a dancer in night club shows, for awhile, so I figure I got past it.

That and the validation from friends and lovers. The message that we were smart, but never quite accomplished enough was harder to get past. That still bites, sometimes.
But, after three generations, at least, of dysfunction and abuse, there is no abuse in this generation.
BTW- KC wants it both ways. She wants to be supported financially, and free to do what she wants 24/7.
Few of us are free to do what we want 24/7. And, most families even healthy ones, won't support a non-contributing member.
