I really shouldn't have to do this. Your parents should have taught you, sometime back when your troglodytic brain was being formed. They should have taught you that when you go to a concert and someone is up on stage playing/singing something, you should
Really, I'm constantly amazed by people who pay good money to go to a concert and talk through the whole damn thing. I dragged the girlfriend to see Bruce Hornsby last night in Pittsburgh. He started the show with about a 15-minute solo spot of improv weaved around "Darlin' Cory" and "A Night on the Town." At least I think he did, 'cause the dip shits sitting behind us were talking about something else. Similar things were happening during the opening act as late comers arrived.
Maybe I'm gettin' old or maybe I'm just over sensitive to this stuff. But mostly, I can't understand why you'd pay good money to talk during a concert when you can do it at home for free!
