Are you one of those people who say they never learned anything in high school? Me neither. I learned a lot in high school, but there were some critical topics that the teachers never mentioned. 1) Parenting Carrying an egg around for a week isn't parenting. The sad thing is just doing that class assignment would have already put you "in the know" compared to most other high school graduates. Looking at how you were raised by your parents will rarely prepare you for the real thing, which is why so many people agonize before having kids and then get stressed out when they do. Or worse, they become bad parents.
