That's a huge mistake. You'll burn your kids out if you act like school is in session 24 hours a day. Kids like watching characters act silly on TV and in movies. It's good for them to take breaks from science and math and literature and learn about their world and about other people and how those people interact with each other in a movie or show (even if the characters are cartoons).
Oh, agree with your point a lot. Just disapprove of programs totally devoid of practically any use, such as many game shows (not all) and the new gladiator show. Even some reality shows have use as they show—as you’ve pointed out—human interactions (though oftentimes the participants are hardly average Americans).
