Parenting: The shit ones think they are great and the great ones constantly worry about being shit.

Yes absolutely. To me, bad parenting is giving your kids absolutely anything they want, with no rules or responsibilities, and never telling them "no". Faaaar too many parents raising their kids that way today.

The best ones don't give a shit about you

My favs are the childless person that freely gives parental advice bc they obviously are better at it and will act accordingly.

Dunning Kruger, it affects all aspects of life.

Yep.
