As a kid, having playmates was easyish but having friends was tricky. As an ND intellectual multilingual round peg in a town of unilingual anti-everything square holes, I had acquaintances but no good friends until high school, one or two then, none in uni, though there were sufficient like-minded people that it mattered less, and, from then until 10 years ago, at most one or two.
In late 2014 I bought a Jeep and joined a hardcore offroad group (rocks, not mud). They are the most diverse group I've ever hung with, and I have half a dozen people I would consider close friends and rather more who would drop everything and drive 50km in a snow storm if I needed help.
I lucked out. But to say it was ever easy is misaligned with my experience.
