There are dozens of us! I’m a mom who works in publishing and don’t know a linux distro from a pokemon (other than Pikachu.)

Social conditioning, once again. We’re French, and it’s totally possible for us.
Yesterday, among strangers, at the local lake, my 42 year old friend was topless, playing with her 7 year old son and her 5 year old (naked) step-daughter. A 36 yo pregnant friend was wearing a string bikini around her husband, 6 yo daughter, and in-laws. It was a non-issue.
Not saying all rules can always be broken, but they’re heavily context- and culture-dependant.

My partner of 15 years has a girlfriend of 25 years. She’s been married for 30 years. We’re happy.
