Yeah I think @J is kind of right, although there are many reasons why we spend less time with many people to just enjoy our being together. 

For me, I ended up being a cave person, smoking instead of drinking, can’t stand the folk music. I like to spend time with more people but not with loud German music or beer & german food. 

I feel so different to the „adult“ people in my village, I often think of how to build connection again. I could just visit them and talk to them but their interests are far from mine (expect maybe gardening) this doesn’t feel easy for me.

Also many of the people, who were organizing it, became older and some of them additionally don’t like each other (so won’t encourage each other)

I know there are many people in my age that are bullish on continuing these festivals, but the „why“ isn’t as connected to them as with the previous generations, it’s often rooted in religion. (We celebrate the opening of our church every year)

But the community thing with trading with your neighbors, its definitely decreasing. 

I personally have a hard time to connect with German culture! So I often think about creating my own German culture. 

And as for many things, we shouldn’t underestimate the power we personally have to influence the circumstances especially locally!!
