I was in the target demographic for all those emo/scene/etc etc subcultures back in their day, I didn't like them and was never part of any of them, but now I miss them...
I mean, I would hang out with people who were part of them and I guess I was always secretly fascinated with the whole thing, their imagery and whatnot.
On a related note, I had a crush in highschool who was deep into the whole thing and styled herself that way, the dyed and straightened hair, the makeup, the black and pink clothes, the hoodies with cat ears, the slit wrists, the whole shebang. Now I see her from time to time turned into a completely normal woman and it just makes me melancholic.
Another thing is that those cultures were innocent I guess, it was all about fashion and music and feelings, while subcultures today are all about politics.
