To share my experience, I've never been married or fathered any children, and when I was starting a new job, and getting acquainted with my new co-workers someone asked me if I had kids, I said "No", and the woman who asked the question said "Don't feel bad, you've saved yourself a lot of grief"---thing was, this woman had children and grandchildren!
I am only sharing my experience, and with my life circumstances being what they've been, I found this rather amusing, but I realize that some folks have no kids and wish they could have one or more, so I do feel sorry for them.
