Anger is neither armor nor umbrella. If it were, it would be armor made of bubble wrap or an umbrella made of sponge. Ineffective. Anger can only be used effectively as a weapon against us. But that too is ineffective if we already know that using anger to combat anger is fruitless. Self-control is impenetrable. Our self-control may anger others, but that’s outside our sphere of influence and not worth our time.
