FWIW, it's hard to make deep adult friendships in a place you •did• grow up in. I live literally about two & a half miles from where I was born; have lived in this town all but six years of my life, & in my current neighborhood for 40 years—& I have maybe a half a dozen solid friends, two whom I'd call close, only one of whom is local, & they live in the next town over.
So, yeah. strong adult friendships are hard.
