Turn it off and have a drink.
That's what my wife and I had to do.
By the way the local town email lists were full of rabble rousers calling for students and teachers to walk out of class. This thing is being manipulated at the grass roots something fierce down here. My kid was essentially left alone in class while the Teacher took the students out to protest. We ended up having to pick her up from the office and take her back when they stopped their protest.
Funny how we worry about guns but not what makes a human being want to murder fellow students. From the lib perspective it's OK to hate and want to kill as long as you can't make good on your inclinations. It's wierd
