As Human beings, it is normal to get angry sometimes.
That is how God made us. If we never got angry, we would not be living.
But God also warns us to not sin in our anger.
You can be angry at your friends, family or even neighbours.
Even so, make sure you do not hold grudges until the next day.
If you breed anger within, it will slowly eat you from the inside and finally destroy all your relationships.
Whether you are right or wrong: let go of your anger, and let Gods wisdom guide you into addressing the issue.
Stay blessed and have a peaceful day.
