If you’ve never been responsible for another human being’s safety and care I think it affects how you interact in the world. The people I know who never had kids or had to take care of another person seem really different than the ones who did. Something about having to put your own wants and needs aside because you’re responsible for someone else definitely changes a person. The people I know who are my age (around 70) who have lived their whole lives only being responsible for themselves just can’t relate to what it’s like to have so many other obligations. They get frustrated and upset because they don’t understand why family stuff interferes with plans for things I might want to do. It’s tedious trying to explain why family illness or crises have to take precedence over a social event or something like that. They’re so used to only having to consider themselves that they just can’t understand what it’s like not to have that option. Like they never had to be responsible to pay for raising a child and take care of them no matter what you might have wanted to do instead. I’m not saying that everyone who didn’t have kids is awful or anything just that we’re not on the same wavelength a lot.
