I lucked out with a pretty good birth family. Still, like you, i didn't start to intentionally connect with my chosen adopted family until after my thirtieth year. And the difference between my social life now and my socal life before is huge. Even though most of my chosen family live nowhere near me. (That needs to change, btw.) You're right. Relationships based on shared principles are vastly more enjoyable and fulfilling. And I would add, easier.

P.S. Y'all is a word.
