I think my friends with children are starting to become a bit jealous of my happy childfree life. I say this because I get many more emails from friends telling me that "it'll be different when they're yours" and "your biological clock will start ticking soon" and "you don't have kids because you're selfish."
I think that the fact that the childless and childfree are already paying taxes for public services they're not using like schools is good enough.
Actually you should have every right to feel angry about paying for schools because they are just another worthless government program. Well that should be regardless of your parental status.
I have had it both a very exciting child free lifestyle and now I have a wonderful son. I was told I could never have children so I filled my life with travel and living in many different countries. It was a fun lifestyle but always something was missing often I was disconnected and lonely. When I finally moved back to the USA and decided to finally purchase a home. I met a wonderful guy. Who didn't care that it would be unlikely we would have any kids not that he was against children. However, much to our surprise I got pregnant. I some times reflect on my globe hopping days. But what I remember isn't marveling at the Great Buddha in Japan, touring Pamunjung or living in London or visiting the Orkney's after crossing the North Sea on a massive ferry, or my time in Amsterdam. I remember being very lonely and unfufilled. Now that I have a family I feel much more connected and never lonely.
It is really difficult to explain to someone who doesn't have kids but that is the best way I could put it. It is a personal life choice. If I had a choice to go back to my former lifestyle vs what I have now. I would choose to have my wonderful loving and funny boy.
Still, I would also highly recommend people postpone having kids until they are in their thirties just so they know themselves well enough to know if having a child is right for them. I have friends who are still childless but sometimes I think they wonder if it was the right choice.
