I'm going to be honest.
I think most of you have 'rebel' wrong. By getting into the whole 'rock and roll thing' all you're doing is conforming to a different group and a different lifestyle. You may not be doing what your parents want, what your government wants, what some people in your year want- but you are doing what half the rock scene wants! You are still conforming!
I'm not saying you're doing anything wrong, I'm just saying that you shouldn't call what you are doing 'rebellion', because it isn't. Not only is it still conforming, it's also old. Seriously- do people still think drug use is 'edgy'? It isn't, because loads of people do it.
If you want to be a rebel, do something completely new, say something outrageous that no-one else has thought of, go against everyone's standards and do entirely your own thing. Almsot everything's a rebellion against someone, so you have to really push if you want to be seen as a rebel.
I personally do some of this stuff- I listen to rock and wear the clothing- but because I want to, not because I'm trying to be cool/rebel. I'm a virgin (but I'm 15 so that isn't a problem), I would get drunk if I was with a group who were, but it doesn't really appeal to me that much so I don't go oput of my way to do it. I don't smoke because I think it's a waste of money, and I don't take drugs. Not because I'm against drugs- I think they're OK for people to use in moderation- but because drugs just don't appeal to me. Is hallucinating really that much fun?
I, like most people, have done some rebellious stuff. A notable example if when I wrote part of a story, used my Mother as a test to see if the plot worked and she said that she thought it was sick and that if she read it in a shop she'd wonder about my state of mind. (This was because the book included incest- which I've now erased (not because of the moral issues, but because it didn't really fit with the storyline and was out-of-character for the characters involved), self harm in a school (changed that for same reasons) and bad language (which I've kept.)
