Maybe she's on prescription drugs. Under this video she says, " I'm not on grass nor am I on the fence." So. That settles that question.
If you think this is just one "odd" video of hers you'd be mistaken. Check out some of her other videos on her YouTube channel. We can all rest a little easier at night knowing that "Jules1999" is watching out for us. ;)
I'll give her credit for "putting herself out there" (so to speak). You'll NEVER see me putting myself on YouTube...for which you can all be happy. :)
