I've met people who don't get a lot of joy from raising their kids, and who'd rather be pursuing an interesting and rewarding career, and that's quite a sad thing to see when they're wearing themselves to a nub trying to do both and getting very little satisfaction from either.
My wife and I are on the verge of adopting a little boy from Russia. We'll be travelling to Yekaterinburg, near the Ural mountains, in the middle of winter to do so. We anticipate high temperatures in the single digits.
During the ten years of our marriage prior to this point, we'd socialized with other people who didn't have kids, and we met some very kind and friendly people through NoKidding.net who had made a conscious decision not to have kids.
None of them struck us as selfish or bitter people like this author, and none of them ever held it against us that we were "childless" instead of "child-free." They'd certainly never brave the Siberian winter to go get a kid, but they'd accept our decision to do so.
At least there's people out there who actually put some thought into their child-bearing decisions. Perhaps if more people did so there'd be fewer abortions.
