Jesus responded: "Forgive them. They don't know what they're doing." What if we responded that way when people hurt us?
Forgive.
Jesus: Let your light shine before men. Modern-day Christian: *shoots laser pointer in the eye of someone who disagrees with them*
Be kind to one another, tenderhearted, forgiving one another... - Ephesians 4:32
Don't let grumpy people make you grumpy too.
