Why are people oddly concerned about how someone lives their life?

I just know as a fairly young woman, people threaten me a lot because I think marriage is pointless and I don’t want kids. I get told that I’m biologically worthless past 35, that I’m going to die alone and hit the wall soon.

It honestly is now striking me as funny. I’m over here living my best life and other people are pressed about it 💀 okay
