Some were married in their 30s, a few never married but a decade older.
What was tragicomic was when I was pregnant with my first in my mid-20s, being told by more than one feminist that I was too young, not ready and too early in my career. I said I’d been married for several years, had an employed spouse and had a house - what else did I need? Or was I supposed to wait until I was their age to try to get pregnant and married, with the clock running out? These were women in the STEM fields, engineering and computer science.
Ironically, women on the assembly line and warehouse were very supportive - a married woman with a kid on the way was normal, healthy, wonderful, etc, as long as I didn’t throw up in the clean room.
The rednecks had the healthier point of view.
A few people are both redneck and hi-tech... mostly guys, though (like me).
