Absolutely this. I tried keeping in touch with people, but social media made that actually harder to maintain, then evolved into the shit pile it is. I jumped ship in 2015-2016 and went back to my core group of friends
My “friends” are the people I’d bend over backwards for whether they’d do the same or not (don’t need them to reciprocate), but I’m sure they’d do that for me if needed. With all of us having kids 1-10 years, and living up to an hour apart, and working different schedules, we still make efforts around breaks or holidays to hang out or visit-however brief.
