Open Letter to the Legions Leering

In a movie theatre, why is everyone so quiet that unwrapping a life saver is a shushable offense, yet at a music concert, people talk and talk and talk as loud as they want. Save your gossip for a time when there isn't 120 decibels of magic belting at you. Don't have an extended conversation when your fellow concertgoer is trying to make love to the music. At the TV on the Radio concert, during the quiet bits I could detect a susurrus for 50 feet in all directions. Shut up! Fuck susurrus!
