Some people respond to difficult situations by becoming hostile, aggressive or argumentative.
Perhaps they believe that they have been slighted, insulted or offended, and nothing short of revenge or retribution will even the score. Any aggressive, dramatic or exaggerated reaction to an event is a sure sign that the person has blown the situation out of proportion and is experiencing a great deal of stress. If you take the action personally, you become the victim. Set your feelings aside because this is not about you, it's about how they feel about themselves in relation to whatever circumstances triggered their reaction. Hear them out with an open mind and without getting defensive or resistant to what they have to say.
