Your voice is not talking, nor is it getting across. The loud sounds you make, your yelling, it creates a wall for all your valid points to bounce off and get nowhere. You aren't going to be listened to the louder you get. It won't change anything in her for you to scream, or shatter glass. You seem to continue after she's apologized anyways. Your anger only hurts the rest of us. And in turn, hurts you. It's only you.
