I realized the other day nothing in life prepares you for a functional family. All your books growing up teach you what to do or what to think about if your parents divorce or die or you move or if everyone hates you or if you are adopted or aliens abduct you or whatever. And then there are support groups all over the place for that. So you get a good guideline of how to be dysfunctional.
No one teaches you how to survive a functional family. It's weird. It's almost abnormal. There's something wrong if your family is...normal.
