My wife used to be a high school teacher. She speaks of how she would tell Johnny to "stop talking," and Johnny would snidely reply, "I wasn't talking." Me, I would say, "LIKE, HEY, I JUST SAW YOUR DAMN MOUTH MOVING, YOU LYING BASTARD!!" and my blood pressure would rise and I would go choke the life out of the little prick. That's why I never taught high school, and I am out a free man today instead of in jail for justifiable homicide.It is sort of an insult to not only your intelligence and character but also common decency to state an obvious lie to your face.
