When your daughter has a sleepover for her 12th birthday, do not let the girls play Rock Band. One of them will be Musically Oblivious 8th Grader, and she will try and sing the Beastie Boys' <a href="http://www.youtube.com/watch?v=z5rRZdiu1UE" target="_blank">"Sabotage"</a> like it's a Katy Perry song. A small part of you will die, and you'll never forget. #LFMF
