@Bouffalant It's an outdated way of thinking that suggests that all families are close and loving, live locally and are involved in each others lives - more prevalent in decades past where perhaps it would have been considered to be the joining of 2 families.
This is such a blinkered view of the past. Do you really think that not living close to family, or not being on good terms with them, is a new invention?
It's not that people preferred their family to their friends in the past. It's that there were certain ways of doing things, certain conventions, and one impact of that was that if you just did things by the book, you didn't cause all this hurt and distress and conflict by inviting one sibling's kids and not the other's (for example).
In many cases people to not live close to their family, are perhaps on best terms with their biological family, and are not part of the bygone days of all families living in the same town and in each others lives on a regular basis.
Again this weird misty-eyed view of the 'bygone days' where all families were the Brady Bunch.
I'm not on speaking terms with one of my siblings, whose partner is an evil bastard, and another sibling is a fucking disaster area. We just chose not to have a wedding party at all to avoid all of these politics. It would have caused WW3 if we'd invited some siblings but not others.
We enjoy seeing our friends on other occasions. I have friends who mean the absolute world to me - I cherish and love those friends far more than my siblings or cousins, but I wasn't going to inflict hurt and distress on family members for the sake of "IT'S MYYYYYY PARTY AND I'LL HAVE WHO I WANT!!!!"
There is no rule that says you have to have a huge 'do'. But by having a big event but then leaving out certain individuals, you are of course going to cause hurt and strife.
The concept of family has changed. It is those closest to you that you love. Not everyone who is related to you by blood.
No. What you're talking about there - people who are closest to you and you love who are not related by blood - is friends. People who are not necessarily closest to you, but who ARE related by blood, are your family.
It's not complicated, and it hasn't changed. It's incredibly narrow-minded to think that it's only in the 21st century that people have suddenly discovered the concept of friendship or that everyone in the past spent their entire lives in their family's pocket.
