Apropos of all this, I love the title of the book JL gave me--Text Me When You Get Home: The Evolution and Triumph of Modern Female Friendship. It seems to be a sociologist's happy validation of female friendships from besties and cliques to squads and posses.
For a while now, I've expected my elderly years to be lived in the communal company of women. Whether that's from watching too much Golden Girls (or more recently Grace and Frankie), growing up in all-girls "convent" schools, or radical feminist envisioning, I don't know... yet.
