I was watching the soccer match on TV ( Australia v Greece ) and was getting into the action. During a particularly exciting play I began shouting at the TV as men are wont to do. My daughter then put me in my place. "Don't shout at the TV, Daddy," she admonished. "It can't hear you!"
That shut me up real quick, but not without bursting out laughing with my wife. That should teach me to mind my manners.
