Anger is so much like a fire. It's powerful and uncontrollable and can do so much without making a sound. As long as there is fuel, it will continue to burn. It extends you beyond your norms and standards. It pushes and pulls in completely opposite directions at exactly the same time.
Anger is a mild form of temporary insanity.
And only when that last, minute spark has flickered out does, the flame show signs of fading.
