I'm 3 years older than my sister, and when she was 14 she did similar stuff. I thank God that she turned out alright, but I can't tell you how many fights I got into because she'd get into a bad situatoin with people older than both of us, then call me and ask for help! It culminated one night with me sending a guy to hospitals with a badly split cheek, and a friend of ours getting stabbed before she realised that I was right, and she was on path to disaster...as I say, she turned out great and grew into a great young women!

I sympathize with what you're going through, just remember, if you weren't involved with anything, you're not to blame for anything. Having said that, I know first hand how hard it is to see your sister doing stupid things with people she shouldn't even be mixing with...All I can say is be strong, and keep your head up, keep fighting the good fight!!
