I've heard that "selfish" logic before, applied to those without kids. I don't buy it. People have kids for selfish reasons. It's programmed into their DNA. If anything, its less selfish NOT to have kids.
Sometimes literally. Missing chromosomes make the decision for you sometimes.
That was the first hit. Then discussions about IVF with an egg donor led to a risk assessment decision about a completely different congenital issue that could kill my lovely bride. Not to mention the awkward decision of which relative to ask or whether to use eggs from a perfect stranger.
The congenital issue would have meant we might even be in the even more awkward position of asking someone to be a surrogate and carry to term. Quite difficult. Not unheard of, of course, but not easy decisions or discussions to have with folks.
After that... Which seemed to lead to "not going there"... There were half-hearted discussions about adoption. But we'd pretty much set a lifestyle and lost interest by then.
Back then, adoption costs were out of the question and the no-kids habit just eventually stuck. No major selfishness about it, just a lot of signposts that said this wasn't going to be our path.
Not as a "replacement" for not having kids, but we did dedicate ourselves to helping out financially with kids from places that aren't as fortunate. We treated that donation bill as non-optional even when I was out of work for a year, and we enjoy seeing photos of the happy teenager the oldest of those kids has grown up to be.
The world got smaller with the advent of the Internet and she found us on Facebook and said hello, even. We've chatted and exchanged pleasantries and photos of life.
If she ever gets an opportunity to travel, maybe she'll stop by someday when we are old and grey for a cup of coffee or tea and a conversation. I doubt we have any real clue what our seemingly minor fiscal support did for her life.
So... Yeah. Programmed into the DNA is sometimes quite accurate. No kids. No plans for kids. Happy to spoil the nephews and what-not.
We don't treat the dogs like they're kid replacements, like some do, and certainly not to the extremely weird way a few do, but with no kids around to blow the budget, the pups are certainly a little more spoiled than the average family pet.
And an airplane. Or part of one anyway. That's kinda nice. It won't ever be "teaching it how to throw a baseball in the backyard", kind of nice... but it's nice.
We'll stash the college fund away for paying for non-abusive, non-evil people to take care of us when we are really old, I guess. Maybe a big trip someday to see stuff. Who knows.
Just trying to enjoy whatever the dealer deals from the shoe...
