If you try to stage dive multiple times and it doesn't work then why keep trying? If I was in the first few rows and someone kept jumping on everyone over and over again, I'd end up getting pretty pissed off personally. People go to the shows to have fun, not to be used as someone's personal amusement park ride.
Am I alone in disliking stage diving? It seems like they're focusing so much on jumping into the crowd they aren't really enjoying the experience, these kids are just running all around the stage, knocking shit over and crushing people in the first few rows :/
