Why apologize lol

Why do people that don't have kids, or never want them, always apologize to people that have them when they bring it up 😅 girl idc. Live yo life, be free, spend your money on you, or your fur babies, or whatever else you kid-less people do. None of my beeswax and don't be sorry you don't want to live the same life as me...it's ok I promise.
