I feel ya dude but honestly I'd rather be surrounded be a bunch of valley girls and preppy boys than a bunch of yuppy white people deciding that they are just suddenly gangsta and we now live in the ghetto. (that's my situation) lol. seriously I do feel your pain though, me and my friends used to walk around all the little valley girls while they were talking and I'd make fun of them in my fake annoying valley girl voice it was halarious, they didn't think so but they weren't supposed to so it was quite entertaining for us. that was pretty shitty of your sister, but don't take it to seriously she's just being a teenager (dramatic) I'm sure she wouldn't have said it if she knew it would hurt you that much.
