I was just thinking about this subject. In particular there were 5 girls I knew who were unusually beautiful. None of them got married out of high school. One married at age 37 and has a baby. I bet she is a good Mother but I doubt she will ever have another.
None of the other 5 ever got married and a couple are now too old to have children. Oddly enough, I think they all would have been good Mothers, they were just raised in a time when girls were expected to have careers and a cat.
The reason I was thinking of them was partly it seemed such a waste that they did not pass on their genes.
At 30 I had a dog, the upscale Manhattan lifestyle, and no longing for kids of my own. Isn’t that what nieces and nephews are for? At 37 I was blessed with a baby. Like that so much, I had 2 more at 39. We never know what life changes and surprises God will hand us. He’s funny that way.
