I'm probably about as old as our Twitter friend here and I don't know what she's talking about.  "Old people" are the only ones who truly know how to enjoy a show.  Most of the others just stand there with their iPhones or they talk or take pictures of one another, totally disregarding the fact that there's excellent live music in front of them that someone (probably their parents) paid good money for.  Instead of listening to the show, they focus the event on themselves while distracting all the people who care to be there in the first place.  Now, I've been known to take out an iPhone and/or cheer loudly during a concert; I think everyone has done that but what I see in the young concert-goers is a lack of courtesy for the people around them.  It's a shame really.  At Wolf Trap, a man in the same aisle as me got up twelve times.  Literally twelve times.  Each time, he bumped and pushed his way through the crowd.  It was very rude and it interrupted the listening experience for everyone.  I don't know about you all, but when I see Grace and the boys performing as well as they do, I am captivated.  It's kind of like a trance; I get lost in the rhythm and the music and I stand there in awe of what I'm witnessing.  When someone bumps into me, it sort of throws me off--like it breaks the spell.  If it happens once or twice that's fine but to have it happen several times in two hours was insane.  The man could not have gotten any enjoyment out of the show, either. Between people like that and all the teeny boppers up front who spend the whole night taking pictures of themselves the only conclusion I can come up with is that it seems as though people just go to concerts just to say they were at one.  It's like a symbol of status or something.  Yet they don't give themselves the opportunity to appreciate the show.  Sure, the kids with their phones screamed loud during "Stars" and "Paris," but the rest of the time they seemed kind of disinterested. I'm glad GPN are professional about it all; if it were me performing I would have told all the little girls to put their phones away.
