Well that's messed up, man. I'd at least take a break while you sort this out. But seriously, if that isn't a prime example of the "pot" calling the kettle black, I don't know what is. If they did it at your age, who are they to tell you not to do it? Lol, well, they're your parents, so you have to follow their rules, but at the same time, try and talk some sense into them without offending.

Maybe mention something about thembeing slightly hypocritical, or how it's totally harmless and doesn't always lead to you ending up naked in the gutter. Promise them that if your grades slip at all, then you'll give it up.

I dunno, that's all I got. Good luck. ~
