I agree with you at times about some of the attitudes Ive seen at Met's shows. Im 43, and female and sometimes I see stuff where I want to shake my head and go grow up already. I never got into any of BS at shows when I was younger; Ive always gone to shows to appreciate the music, the musicians and enjoy-- not be a destructive idiot or bother other people. Going to concerts should be about that...not seeing how drunk/stoned etc you can be and make an ass of yourself. I understand music theory, and dont go to a show just to "be there" which many people do these days. I will feel honored to see
