i don't want to come off as being.... an ass, but basically, its fairly clear to me that you idiolize kurt cobain, too much in fact.
don't get me wrong, i like nirvana and kurt was a great songwrite IMO. But it seems that you are purposefully following his trends beuc you deem them as cool. I did petty vandalism stuff when i was young, but i ralized it was lame and there were better things i could do with my time. The only reason i let my hair grow long is to donate it. that and i hate regular hairbuts.
but thats besides the point. smoking pot and breaking stuff becuz you think its cool is really really stupid and if you met kurt cobain he wouldn't praise you for it, in fact he would probly call you and idiot.
keep in mind, he was a junkie, rarely showered and couldn't really be trusted when he was thick in his disease of addiction. get right with yourself.
