Sort of.
It depends partly on where you live and what the local culture is.
I don’t have kids, but I do understand that parents live in a different emotional world than I do. It’s like - I don’t have to have a broken arm myself to know that a broken arm hurts like hell (which is not to imply parenting is painful all the time!). I can see that it hurts. Likewise, I can observe that parents are different, and react differently, than non-parents do in some situations. Having observed the grief of parents who lose a child to death up close I can also understand that it’s a level of grief and despair I have not experienced myself, even if I have lost that exact same person (sister and nephew).
What does bother me is when parents consider this to be inherently superior - it’s not, it’s just different. The emotional state of being a parent isn’t always a positive (see WhyNot’s comment about constant worry/terror). Sometimes, you need to be objective and it is extremely difficult, sometimes impossible, for a parent to be objective about a child. There are downsides as well as upsides to parenting. People tell me how joyful they are about their kids, but then I think of one of my sisters who has one dead child and one severely brain injured child… the joyful parts of parenthood are all in the past for her, there is little but grief and worry ahead for her. For the rest of her life.
So, yeah, I get that when your child is hurt/unhappy/sad/crying/ill/etc. it causes you pain. I can see that. You don’t have to underline it by looking at me and saying out of the blue “you don’t get it. You’re not a parent.” That’s a hurtful statement, whether it was intended to be or not. It implies I’m clueless, unobservant, unempathic, and I’m that way because I’m not a parent.
That said, us non-parents are well aware that your parent status occasionally impels you to say clueless things. Just like our non-parent status does the same to us.
On the other hand, I have had people tell me to my face that I could never be happy unless I had kids. That I wasn’t a real woman unless I had kids. That I should abandon my sterile husband for a man who could give me kids, as if they only purpose in life of my best friend was to be a convenient sperm donor for me… these are not kind things to say. Fortunately, they are rare statements in my life but yes, some people are that thoughtless and, dare I say it? stupid.
WhyNot has never experienced being a childless adult. She can intellectually understand what it would be to be a 50 year old woman who has never had children, but she can’t grasp it on an emotional level. Once you become a parent you’d can’t un-become a parent. You might lose your child(ren), but that is different than never having had children. If you had your kids relatively early in life you don’t know what it is to be middle-aged without having had children. It’s a different mental state - neither better nor worse just different. It’s also becoming more and more common these days.
And no, not having kids at 20 isn’t the same as not having kids at 40 or 50. I’m not the same person I was at 20 or 25. At that age I thought I understood what I’d be like later on, but I didn’t, because I hadn’t experienced the years between.
