Physics

Apparently I walk around Whatcom with a target on my back. I honestly don't know what I do but my physics teacher really doesn't like me. I was in class today and my cell phone goes off. OK, OK I know bad but I am the only person that has gotten kick-out of class. Other people's phones have gone off and she doesn't do anything. Its like she wants to see me fail. Why me? Am I an easy target?
