Psa 4:4 Be angry, and do not sin. Meditate within your heart on your bed, and be still.

Some says that a Christian cannot be angry but interestingly the bible says be angry but do not sin.

It reminds us that though we can be angry just don't sin when you are angry. I wonder whether the solution when you are angry is to stay away since the solution seems to be meditate within your heart and on your bed. Ie not in public, not at others.
