I mean that’s just life. Why is this a bad thing?

You go through periods of time and when that chapter ends you move onto the next chapter.

Expecting a band of misfits to stick together for 40 years is what is atypical.

When I was in college I had a great group of friends but after we all graduated we went in completely different directions, industries, and live vastly different lives. The friendship was perfect in the moment but now I’m in a new one.

Better cultivate meaningful relationships instead of reinforcing a sick institution like the fake office friendship.

Your family, friends, neighbors.

If you move, are you upset your neighbors don't travel with you? I sincerely don't understand the point you were making. Obviously having a network of family and friends matters too, but your children will grow up and leave. Your friends might leave too. Do you think those relations were a waste of time as well.

Most things are ephemeral in a human lifetime. That's why it's better to appreciate what you have now, in the moment; than lamenting something in the past.

I still hang out with neighbors I had decades ago.
