NOW I think THAT'S a SELFISH reason to have kids......so that you can have somebody to help you when you get old?? I'll bet your kids will be happy to know that.
I stated an observation. There are many old ladies living in FL and AZ who have no one to take care of them. There are many apartment managers who make regular trips to make sure their lone tenants are still alive, because no one else, not a single family member checks up on them. Yes, they find dead bodies. Sometimes they have no one to notify.
How about, it is nobody's business as to which couples have children and which don't. That is between them and their God, if indeed they choose a faith.
It is certainly none of my business, and I'll be damned if I'll judge their union, just as I hope they'd respect mine.
