I have a weekly D&D game with my favorite aunt and uncle, as well as my Dad and my cousin's husband.
The latter runs one weekend, and I run the next, completely separate games of course.
I'm 51, my dad is 79, and his sister and her husband are a few years younger than he is. No idea on my fellow DM, I suspect late 40s.
If you find a common thread to hang on to, you can have a great relationship.
In this case, my aunt and uncle knew I was a huge weird nerd whose dad introduced him to D&D at 7 years old, so they thought to invite me when their daughter's husband made a game for them.
Seven years later, we are still at it and I run a game for my friends as well.
These relationships can be nurtured, as all can. You just have to find and maintain the why's.
Even people who don't give a crap about birdwatching may still love to see the birds their old friends spot.
But to further your point, I don't make much of an effort for those relatives that I don't have much in common with.
This year's Christmas present is a box of homemade fudge, rice krispie treats, and spicy chex mix, all homemade.
That's the effort I put in for those I don't have in my weekly or monthly life but are extended family.
The People have stated their priorities. If the rest of the machine refuses to work to fulfill those promises, they are betraying the people.
Promises are fulfilled through work.
Wishes come true. Terrible framing.
