I’ve found tribes of sorts at different times in my life, I felt it with my running club many years ago, that was shared enjoyment of running, I got a lot of camaraderie from that. But I no longer do that now so lost it.
I have it presently in volunteering, the other volunteers aren’t alike but we share the passion for our volunteering and there’s camaraderie there. They aren’t close friends but it does feel like community.
So for me it’s been shared purpose or passion.
That’s interesting about your dna and eye shape, it’s amazing how dna can seemingly skip generations like this.
