When in doubt, start with generosity.
Assume the other person meant no harm.
Show an act of kindness if it is in your reach.
Share a smile.
Give a hug.
Be easy on those who've had a hard day.
Recognize your privilege and use that recognition to drive your desire to give back.
Take a moment before returning anger.
Practice gratitude - both silently, and with those around you.
Share a kind word.
