"Making teenagers depressed is like shooting fish in a barrel" (wods of wisdom from The Simpsons).
I have quite a few piercings. My mother thought it was some kind of self-mutilation at first, but now I think she's just happy I didn't get a tattoo when I threatened to. As am I.
I couldn't be a goth now. I find most of the music dire, although get a kick out of some of the industrial stuff (perhaps because it's a dance music precursor of sorts) but now I like happy music.
