Meh...
While i do not agree with cutting oneself, and many of the other "emo" ways, i didnt really find this that funny. Sure, its kinda wierd to cut yourself, and their clothes may not be all that appealing, but its the lifestyle they chose. I Also noticed you said you're a "peer mediator". If you have to talk to "emo" kids all day, and do not like their "whining" then why don't you STOP talking to them. And if thats not possible, just quit your position.
What am i saying...thats a bit too logical. my bad.
PS: Those clothes looked more Goth than Emo. I've noticed Emo is a lot about tight clothing...
