Anger
Staying angry with you is how I protect myself from you. Refusing to forgive you is not only how I punish you: it is also how I keep you from getting close enough to hurt me again, and nine times out of ten it works - only there is a serious side effect. It is called bitterness, and it can do terrible things to the human body and soul.
Barbara Brown Taylor
It takes two flints to make a fire.
Louisa May Alcott
Heav'n has no Rage like Love to Hatred turn'd,
Nor Hell a Fury, like a Woman scorn'd.
William Congreve
In times of great stress or adversity, it's always best to keep busy, to plow your anger and your energy into something positive.
Lee Iacocca
When angry, count four; when very angry, swear.
Mark Twain
