I didn't exactly say "hey congratulations!!" to these women, I just said good on you for not having kids just because you think you should and because a worrying number of people seem to assume it's the next logical step to take towards complete life fulfilment once you are in a stable relationship. I also said that in my view having kids is not the bowl of cherries that some would have you believe it is.
I feel that the people who would feel "patronised", "irritated" or "pissed off" by me saying this to them are more than likely the ones who do not have children but deep down really wish they did. That's sad and if I knew that any of these women felt like that I wouldn't ask them. I know that's not the case with any of these women though.
My work colleagues didn't turn a hair when I said it and it wouldn't bother them because none of them are harbouring any simmering resentments or inner torment. They are totally ambivalent about chidlren, they're quite happy to talk about them, make all the right noises and ask polite questions when someone brings one into the office or to vist with them, babysit and buy gifts when their friends and family members give birth to them. They are not secret child haters who moan about babies and children screaming in restaurants, or bitch about their colleagues who have children wanting time off in school holidays.
They're just nice, normal, well balanced friendly women who happen not to want children of their own out of personal choice.
None of them are the sort to take umbrage just because someone asks them a question and they are all the sort who would tell someone to butt out if they thought they were overstepping the mark.
Out of personal choice I have only one child and over the years many people have asked me if I'm planning to have any more. I don't get remotely offended by the question and am quite happy to tell them that we've only ever wanted one. Sure it's none of their business to ask but so what if they ask? I know a lot of people in my situation do get deeply offended by the question but again, that's usually because it touches a raw nerve with them because they do want more children but can't.
My colleagues aren't offended/insulted and don't feel patronised because, like me, they're not bothered by the question or the answer.
