== What experience can adult men (25+) go through that is enough to build a lasting friendship?==
Maybe fatherhood. I’ve had some of that experience with friends I’ve made through my kid’s preschool.
This week I read an article about a local club for new fathers in Chicago. Kinda of a similar concept, friendship through shared experience.

I think you are right - I am a total fucking weirdo, irredeemably strange, but as soon as I had children suddenly I could talk to other dads. Unfortunately, men cannot yet reproduce clonally.
