Namechanged for this.
I never talk about it out loud, but I'm so pleased with myself for not having children. I think about it every day. It's at the back of my mind every time I talk to someone with kids, or see or hear a child.
I respect children and want them to be safe and happy (part of my job is to fundraise for children's community projects), but I never want them near me, and never, ever want one in my home. I can't fathom what possesses people to have children by choice, especially in this day and age. To me, there are plenty of people who are already alive who could benefit from my skill set, so that's what I apply myself to.
When people with children talk about their fantasy of a perfect day/life, they very often describe a life just like mine. Quiet, clean house, doing as I please, my money being mine alone, making modest but carefree travel plans. I have never once fantasised about a life with children, it looks positively masochistic.
When I was younger, people told me I'd regret not having children. One people even described it as "cheating". Now I'm older, people are starting to admit that they think I made the better call. I pretend not to know what they mean and say "Oh, I'm sure that's not true! Everyone's different!". But I agree.
When people say that childfree women "don't know how hard it is to be a parent", they're wrong, I do know, that's why I didn't do it. When people say I "don't know how good I have it", I do know, that's why I made the choices I did. I think about how good I have it every day I wake up!
I'd go as far as to say that I'm smug as fuck. But it would be rude of me to let on in real life, so I keep it quiet.
