Never Have, Never WillI'm a vehemently childfree twenty-something woman and just never, ever had a maternal instinct. Growing up, my baby dolls got mutilated and painted over and generally crushed into oblivion...meanwhile, my stuffed animals remained pristine and were taken care of. No shock, I always hated kids and loved animals, and nothing has changed as far as where such instincts lie. What can I say? As far as I'm concerned, there is absolutely no benefit to having kids - unless you're stranded and starving on an island or in the mountains, in which case you can turn a baby into some nice cutlets. :)
But besides that, I cannot fathom why anyone would voluntarily sign up for an unpaid job with no vacation and no perks - one where you actually have to pay money to do the job, too. And if you do the job poorly like most parents do, you may end up with a little sociopath who never leaves home. And for what? So this little ungrateful beast can tell you it hates you on a regular basis? So it can get knocked up and fob the resulting bastard off on you? So it ages you thirty years and makes you a desirable mate only to an equally diaper-whipped significant other? To hell with that. Having kids is not worth the trouble, the cost, the bodily destruction...they are worthless and I hate them. And those are just the normal ones - don't evne get me started on the retarded or undisciplined ones. I want t kick the normal ones the second they open their mouths.
If my choice makes me selfish or immature or any of the other things parents themselves are that they accuse us of being (projection, in psychology), then fine. I would rather be immature and selfish by some idiot stranger's standards and be happy than be mature and selfless by said idiot's standards and also be miserable. Life's too short to spend it doing stuff you don't want to do, so why bother? I don't want kids, so am I supposed to have them because society says I have to to be normal? Screw that.
