Firstly, you have to control that tongue. Start by answering other angry people softly and don't bite on the bait. Watch something extraordinary happen. The more you answer them softly, the more likely it will be that they will run out of steam.
Now, this will take some time and a lot of practise before answering softly becomes a habit. But the great thing is that when it does, you will be pleased with the way it affects your life, relationships and future prospects. Get rid of that anger and make place for God's love. His special supernatural love is the real answer to controlling anger. The perfect solution to a defeatable problem.
Be blessed - God's way!
