I would not say dysfunctional per se. I would wonder do the parents or kids not have any friends or spouses to occupy their time with? Are the parents dying or in poor health so the adult kid(s) have decided to spend as much time as they can with them before they die? Or are the adult kid(s) the care givers of their sick parent(s)? I would wonder why myself tbh.

In a pretty hostile world, why not?

Follow your belief and let others follow theirs.

No it’s quite the reverse of a dysfunctional family. The fact that they are interacting and socialising with each other on a daily basis proves that they must enjoy each other’s company and are functioning normally. I have friends who have similar relationships with their children, most of whom are now in their forties and fifties. This can only happen when all the members of the family live close to each other, more likely in families where the children don’t go to university and find work and partners close to home and where their parents live. My children went off to university and after graduating, found jobs and partners in other parts of the country from where they lived with me, so it was never going to be an option to hang out with them on a daily or even a weekly basis. Personally I would find the sort of relationship you describe as being too close, but that is from my own perspective of raising my children to be independent adults who can function and feel my love without the need to speak to or see me constantly. Dysfunctional families on the other hand do not communicate or interact with each other properly, are generally unhappy and would not voluntarily wish to spend time together.

Some families are very close and some are not. I think that if you are very close it is so much harder when something happens to one of the family. Family doens' only have to be siblings and parents, one can choose another 'Family', very close friends can be 'family' too.

In England, up to the sixties, it was very common for an extended family of grandparents to great grandchildren to live in the same village, within easy walking distance and often only a few houses apart. Then, such close family relationships were very common and many family members would meet in a local pub (bar). It is only with better education, greater freedom of travel through car ownership and young adults traveling / moving to other areas for university education and higher paid or more interesting work that has broken down the closer family bonds.
We now have many elderly people alone in their homes and having few, if any, visitors, and so many young people with mental health issues now; back then there was a family networkm an inbuilt support system always someone to help the elderly,always someone to listen and talk issues through - .
I am not saying things were better then, simply that things have changed, with some benefits, but much has been lost.

No. Some families are close. It's not weird to have normal human bonds. Sorry but people who can move on and leave their families behind are the damaged ones IMO and I ought to know.

It's the word "party" that's getting my attention here. I don't think there's enough information provided in order to fully understand what's really going on...

But, if a 50 year old is going out a few nights a week and weekends, with his or her parents, going to bars or drinking and smoking weed with them, I do think that's pretty weird.

No close family it's cool

I have close friend who is one of 4 and has large extended family. she and her siblings and spouses eat one day at their granmothers and her husbands family does a Saturday breakfast, he only has a sister. It is odd to me, but I am an only child and have 2nd cousins, but other than them and my 2 children have only a step sister. I met as adult, who I love. I had friends as family to me. I did realize when young it was odd. Where I live now family being close is not unusual. I find this friend and her family wonderful, just not the culture of mine who had more only children than not.
I would not say they spend all their spare time but they are close. Most of my life, even as a kid, friends' family kind of adopted me, so that was nice.All my long term relationships have been with tight family relationships, which I loved.

Why do you care?

Is this cuz your kids won’t go home? (Just kidding)

That is completely personal and I imagine hugely influenced by culture and subculture. Some might think it would be really odd if you didn’t spend a majority of your time with your family. I think until recently (in terms of human history) it was the norm for multiple generations of a family to live and work together with children only leaving the nest for marriage or because of overcrowding.

I believe it’s a very positive thing and works well for many families.

Maybe it's a farm small town family pattern or maybe the 50's kids are staying close to the 70s inheritance....a big kegger is planned for the wake to keep the party going around the grave

It's a Southern thing for sure, and also the way it was done until recently. Families mostly socialized with family members. My mom used to constantly tell us that friends are temporary, but family is forever, so treat each other "right."

But now that both parents typically work long hours, whenever people get a holiday, many want to be with their relatives since they seldom get to see them. I always saw this behavior as a red flag, indicating that person is a redneck. Educated, wealthy people typically spend their vacations with their families in the Bahamas or Ceylon, not at family reunions.

it's a good thing. Life is more rewarding if lived for others.
