Lately our nine-year-old son has been into watching musicals, where people sing and dance with the kind of joy that usually only comes after being over-medicated. Maybe these people are that happy. Or maybe they just got their dosages wrong. At some point we will have to explain to our child that people who spontaneously start singing and dancing in the middle of a store risk being tasered by security. Location is key. The choice of setting can mean the difference between a criminal record and a Tony Award.
