This is a quote by Brigham Young. I found it in something with no source, but I think it is powerful. Choosing not to be offended has to be the happiest, healthiest choice we can make.
"He who takes offense when no offense was intended is a fool, and he who takes offense when offense was intended is a greater fool. There are two courses of action to follow when one is bitten by a rattlesnake. One may, in anger, fear, or vengefulness, pursue the creature and kill it. Or he may make full haste to get the venom out of his system. If we pursue the latter course we will likely survive, but if we attempt to follow the former, we may not be around long enough to finish it."
