I agree with this and I think it has a lot to do with free time. In college, if I was asked to go to a party by an acquaintance, I'd probably say yes. Once I started working, getting into serious relationships, and adding more day responsibilities; the answer changed to no. I'm at capacity with how many relationships I can meaningfully maintain, but I'm happy with the ones I have. That's not to say the acquaintances don't have value or I don't like them. I'd just rather go to a tech talk or spend time on one of my hobbies than go to a social event without any of my core friends. It's not that I don't enjoy the social events, they just have fallen far lower on my list of priorities over the years.
