I appreciate the perspective, and I certainly don't hold anything against the folks who have prioritized other things in their life. The difficulty I've found is often when there used to be some activity or hobby you did with someone, which then becomes harder to continue doing without them. If your usual tennis partner moves away to start a family, it's not just trying to find a new friend, it's trying to find a new friend you enjoy playing tennis with, or upending your schedule to now play less tennis, or stop playing tennis at all.
