Picked up a book from the used book store today. It’s called Guyland, and the cover flap notes it’s about initiation rights to adulthood that seem to have gone wrong. It was published in 2008.
The cover flap says, “the passage from adolescence to adulthood was once clear, coherent, and relatively secure: in their late teenage years and early twenties, guys ‘put away childish things’ and entered their futures as responsible adults.”
I don’t know. I think male maturity has a lot do with just calming down. And my understanding is you can’t do that in your own nuclear family for whatever Freudian/emotional reasons. So you need your cousins or friends to really do it.
