I’m friends with a couple in their late 70s who never had kids. I have no idea why, but they’ve traveled the world and have lived the most interesting lives. I’ve now seen her response to people quite a few times, it’s always the same answer. She just came up with a canned answer that I imagine has been very painful for her over her lifetime. I do think she over explains. When people ask if she has kids I want her to just say no, but instead she goes into an elaborate story.
I’m a big believer that things are none of my business until you tell me otherwise. And I certainly think if you don’t want children you shouldn’t have them.
