At 13 and 15, we decided the girls were old enough to start watching The Big Bang Theory this winter. They love it. (It doesn't hurt that we know/are people like that either.) My husband wants a copy of the Friendship Algorithm for his classroom. He says his students need the advice. I haven't got around to mentioning exactly how often it's re-run though. I don't want them watching it for 6.5 hours a week.
