This is a good point.
I am retired now and lucky to have my (now adult) children living nearby. Every Friday I cook a large pizza dinner for everyone, their spouses, and their children, and any friends they want to invite. I will always be an introvert, but this weekly meal is the highlight of my week.
The difference between this and what my parents did is that I host for my own pleasure and for what it does to bind the family together. I don't expect reciprocal invitations, and no obligation is ever implied (I hope).
Yeah that's really good, and I agree with the sentiment.
TBH, if I were to retire today, I'd love to do that, too. I only have one son, so probably it's not going to be a big dinner, but I'd also invite friends of the family, too.
This is awesome. I see this as a form of leadership (brings people together, its not easy, not enough people do it, no expectation of reciprocation, etc).
Hopefully it helps the next generation stay connected and maybe your kids pick up this habit when older and it becomes a tradition.
