“In other cultures, men and women have initiation ceremonies and rites of passage for boys and girls. They are all designed to re-wire the children’s brains and change their perceived identity from child to adult. Admittedly I know more about how they do this with boys than girls. With boys they do stuff like send them out with a wooden spear and not let them come home without a dead lion. With girls? I don’t know. Whatever it is I’m sure it’s equally as cool as the lion thing. I’ll read up on it and report back.”
