I vote more that it's about the childless who don't get how fun parenting is, how proud little milestones can make you, and how family members really DO want to hear about most of the things our kids do. I didn't give a shit before I had kids; now I totally understand it. This is more a matter of self-absorbed assholes who think the way they view the world is the only valid one.
Try lightening up, folks. Get out in the world. Turn off the PC. Take a walk.
