I know.
Even “back in the day,” in the deep past ... like my grandparents’ generation ... a 14-year-old girl and a 20-year-old man would have raised a few eyebrows. “Okay, you can get engaged ... but you’re going to be chaperoned until she’s 17 and you can get married. Are you going away to college, young man, or have you considered a stint in the Navy?”
In those days, the couple would have gotten married, even in a class where 14 was fully grown up.
In “These Happy Golden Years” Laura Ingalls Wilder talked about how Almanzo courted her. Mind you she was about 16 and he was 26. When they did finally she was 18 and he 28. Their courting was mainly buggy rides (just the two of them) on Sunday and him escorting her home from church. Kids today would have found that kind of date quite boring.
My mom was married at 15. Her first (my oldest brother) wasn’t born for a few years, though (she was 18 when he was born).
I’m in my mid-40’s, so it’s not “that long” ago..
