Pretty much life as it always was... Sounds to more like people are stuck in a comfort zone Or in a TV world of the 80s/90s with sitcoms like full house.
My point is, I can get the full experience (namely the called out smiling) without them being mine.
I can tell you from experience, it is different if it is your own child.
And, as much as I don’t have the experience to say how my life would be different with a child, you appear to lack the experience to know how your life would be different without a child.
I have over 25 years of childless adult life, an experience many of my parent acquaintances don’t - can’t - have. It’s been a fulfilling life.
That said, I appreciate the sentiment. Thank you. :)
