And punks... though that may not be everyone's cup of tea. I'll hang out with anyone really if they're decent people. Never liked social divisions.
At first we (metal heads) were at war with them, back home. Friday night brawls at the skate park and all... I was a bit young to really get involved but in retrospect, it wasn't all that serious.
But soon came along bands which bridged the gap between their culture and ours - Slayer, Metallica and all those guys. I for one was quite happy because some of my best/most interesting friends happened to be punks.
