Anger begets anger

An employer gets up one morning and bawls out an employee. The employee is resentful and hurt. When he goes home, he is angry with his wife. The wife, feeling misused, slaps their child who, in turn, kicks the family dog, who chases the cat down the street ... and so the story goes on forever. Anger and violence reach out to capture the next one until the whole world is caught in their grip.
