I clicked a news link about the new No. 1 most-watched video of all-time on You Tube. It turned out to be Justin Bieber's "Baby" music video. Having never heard him, I clicked play. By the time it was over, Ethan was dancing on the couch signing "Baby...baby...baby," Ryan had come over and put his head on my shoulder to watch and Lily had climbed up on my lap and was yelling "More! More!" What have I done?
