While it should really be your kids reading all this, there is no harm in you educating yourself on what they will be up against. If they are like my old classmates, some kids will prefer blissful ignorance plus lots of things will probably change over the next few years anyway, but you can give them the new editions before fourth year when they start getting antsy. And if you just want to read something for the entertainment value, lots of people with no personal interest in acting or the business have found Jenna Fischer’s book to be hilarious.
