Unless your kids don’t like you. Really the idea of breeding so you’ll have company in your dotage and genetic immortality is pretty lame, shallow and ego driven. Kind of funny how many people call those without kids egotistical and shallow then throw around their even more egotistical and shallow reason to have kids.
If you wanna have kids great, enjoy them. Not everybody likes kids though. I have never liked kids, I can remember as far back as age 5 clearly preferring the company of adults. Don’t like em, never liked em, never gonna like em. And if you don’t like that TFB.
I don't think those are bad reasons. Not at all. They probably factor into many people's decision to have children. Then one learns broader and more altruistic aspects as one goes along, inasmuch as parenting is many people's gateway to adulthood, in the noblest sense of the word.
