Scene and Emo are similar styles, i would call it categories, Emo stands for emotional. You listen to hard rock and emotional songs if ur emo. Scene is kind of the same, with the difference that scene people are not that emotional. Some people say that the difference is that emo people cut themselves. Sometimes, sometimes no. Scene have mostly a colorful hair.
Im not a scene/emo expert but im kinda scene. I know as much emo as scene people and i know a little. No need be called fucked up lifes, or fags or anything offencive just cuz theyre different. And no ones different, everyone is special.
