Holding anger only hurts ourselves.

Holding onto anger is like grasping a hot coal with the intent of throwing it at someone else; you are the one who gets burned. - Buddha

from buddhistmoms.

So, I say, let anger flow over you like hot water and then it's gone. Meditation and practice helps you know how to deal with anger...kind of like equipping yourself with hot pads or a fire suit or thicker skin, or the knowledge of how to handle hot water so when it flows over you, you are not burned by it.
