Do something the same way for a long time -some less than ten years- and it gets hard to accept change.
Saw it with men when they lost their tennage hunting buddies. Some move away; you moved, marriage changed some.

I would have quit thirty years ago if I absolutely needed buddies.
Had one relative quit who lost his buddies, and the farm they use to hunt. His children were all raised and away. He couldn't take to change.
Saw it with a fishing hole. Fellows were there every week. Got over an injury, so I started looking for new places. Old place would eventually change and be gone.
Went back two year later. The fishing hole had changed. All were gone. I moved on to the new areas on the river I had found. They just left.
Change, it usually comes to everyone.
