"The boy had been sent home from school early on the last day of class for throwing water balloons. He went back to the school with a .25-caliber handgun taken from his grandfather's cookie tin and shot Grunow when the 35-year-old teacher refused to allow him to speak with friends in Grunow's class." But now the Florida Teen Is 'Very Sorry' for Killing Teacher. It's alright then. Sigh. What is the world coming to. How does one come to such an action. I just don't get it.
