That odd one out deal I picked up on too in my experience. It really awoke in me a perception of the whole sense of family friendly vs adult oriented. I realized I had been on an adult only train for decades never contemplating the absence of children as being anything abnormal. I just assumed for the most part they were around just not in the venues or circles I mingled with. Eventually I realized they’re mostly absent never having been born. That was a pretty stark realization I think that hit me when Kaiser released some document about “Children, California’s Most Precious Resource”. The adult oriented world I realized was a diversion into all sorts of endeavors unrelated to continuing the species. There’s a saying I heard like in the last 2 years let’s say—-a place that isn’t crying is dying. Ie no cries of children being heard that group of individuals will be no more in say 60 years.
