Some concerts are sitters, and some are standers. Don't be the asshole who stands while everyone else is sitting.
I hate this so much.
This. I understand if you want to stand up and rock out, but seriously, you're ruining the show for all the people sitting behind you. But, as displayed in the responses in this thread, most of those people clearly don't care much about the way others are experiencing the show as long as they themselves are having a good time.
That is bull crap. I said that if everyone else is sitting down, I will almost always reluctantly do so, as well, but I will ask again:
Who goes to a rock concert and expects to sit down the whole show?
If you want to sit down for a whole performance, go to a play or a movie, not a rock concert.
And for the record, at our Rush concert last night, pretty much everyone in the entire middle section where we were stood for the entire concert. I can't imagine how boring that would have been had we all been sitting down. Not as fun to air drum and air guitar sitting down at a concert, ya know.
And like Zeltar said, if I were on stage performing a rock show and everyone was sitting down, I would think I was boring them.
Also, regarding people whose back hurts them, I am very sympathetic, as I used to have all kinds of back problems, but if your back cannot take standing for a whole concert, you cannot expect everyone around you to sit down, too, just because you insisted on going to the concert, knowing full well that you couldn't stand the whole time. I went to quite a few concerts back when mine used to hurt, and if I had to sit down for a few, I didn't expect anyone else to sit down. Why should their enjoyment be disrupted just because of me?
