Oh my God, me and my friends are total pains in the asses at concerts. We're yelling and and screaming and singing along and jumping around and dancing... I feel like that's the fun part of concerts. I swear to you at one point during the Jay-Z concert when he started doing 'Bonnie and Clyde' my legs actually gave out and I fell onto the floor, I was so excited, hahahaha.
People usually don't complain though because we're not obnoxious about it. If anything we've always been told at concerts that we really made everyone around us energetic etc.
