Till the anger is gone

"Too angry to see straight" means exactly that, you can't see clearly to stay on the right track. Don't make a decision or react when you are angry that you will have to live with even after your anger has calmed. Even an angry word can do damage that will never go away. So if you find yourself too angry just relax a moment quietly being still and silent till the anger is gone for if you don't you will deal with the damage for far too long. A moment of silence may calm the storm and spare you from a lifetime of damage.
