Refuse to participate in gossip.
Speak positively about others; everyone has a few good points
Let a matter die; don’t be like a cow chewing its cud.
If all else fails; just walk away mentally, if not physically
Extend grace when someone does something irritating
These are just a few ideas that come to my mind. I am sure there are other things that can be done too. As Christians, we must handle drama in a way different than the people in the world so they will see a difference in us.
