I’m glad you recognize this. I am shocked to find how many people say “I don’t know what I’d do if I never had kids” or something along those lines. It alludes to people having kids as a next step to adulthood or to avoid boredom. Or the ole “who would take care of me when I’m old if I didn’t have kids” - the most selfish one.
We’re not having kids and that is almost always the first thing people say, who will take care of you? What a selfish thing to thrust onto another human.
