Oh my god you people are stupid... FOURTEEN AND YOU'RE WORRYING ABOUT HOW BIG YOUR BOOBS ARE!?  Don't worry... They keep growing till you're about 24, 25 so you've got a ways to go little girls!!!!!

This happened to my boyfriend in high school, it ended up being that he had had a very mild stroke and had bells palsi.  This can happen at any age and the side effect is that your (I think left) side of your face goes numb and you can't control it...
