Barb isn’t a boomer. She was born October 19th, 1941. Auschwitz wasn’t fully operational. The Kidō Butai was still in port, preparing to sortie for the strike on Pear Harbor.
From what I’ve heard, culture changed rapidly between the last of the silent generation and the first boomers. The first true thots came about in the ‘60s. It was like how quickly culture changed when Web 2.0 happened. Barb turned 16 in 1957. So Bobcat started her prime ten years before the Summer of Love. In the south, the changes happened a good 5-10 years behind the west coast. So Barb being promiscuous back then would’ve been like an E-girl in 2015 traveling back in time to 1997. In 1950s Virginia it would’ve been normal for girls to be virgins in highschool and get married right after graduation.
