Don't, and I'm sure my fellow forumgoers will back me up on this, just stand there. Other people will, as they did when I went to a FF concert (p.s. it was totally fucking awesome), and if you so much as bob up and down you might just feel like a moron. But let me tell you, I really don't like dancing, and I was moving more than most of the people on the floor in front of the stage, and probably a much bigger fan than most of them too. Seriously though, think about what it must feel like to be up on a stage rocking your ass off and have like 30 people right there, so close they could touch you, standing stock still or nodding their heads slightly and peering up at you through their fucking black square-rimmed glasses. I defended these people in another thread, because I can understand the feeling of not enjoying dancing or whatever, but having everyone just standing around? Not cool. In fact I would go so far as to say: Lame!
So yeah, that ended up being longer than I originally intended. I'm not going to be there, but shake your ass. You know the fucking Furnaces are going to earn it.
